Title:	ENERGY EFFICIENT DISTRIBUTED IMAGE COMPRESSION USING JPEG2000 IN WIRELESS SENSOR NETWORKS (WSNS)
Author:	A.KARTHIKEYAN, T.SHANKAR, V.SRIVIDHYA, SURYALOK.SARKAR, AKANKSHA GUPTE
Abstract:	Restricted computational power, memory limitations, narrow bandwidth and energy supplied present strong limits in sensor nodes are the important points should be considered during the real time transmission of data using wireless sensor networks. Therefore, maximizing network lifetime and minimizing energy consumption are always optimization goals. To reduce the energy consumption of the sensor network during image transmission, an energy efficient image compression scheme is proposed. The image compression scheme reduces the required memory. To address the above mentioned concerns, in this paper, an approach of image transmission in WSNs, taking advantage of JPEG2000 still image compression standard and using MATLAB and C from Jasper. The features provided by JPEG2000 were achieved using techniques such as Discrete Wavelet Transform (DWT) and Embedded Block Coding with Optimized Truncation (EBCOT).Image quality and energy consumption are the two performance parameters should be considered during the image compression and transmission. Simulation results are presented and show that the proposed scheme optimizes network lifetime and reduces significantly the amount of required memory by analyzing the functional influence of each parameter of this distributed image compression algorithm.

Title:	ONE-TO-MANY REVERSIBLE MAPPING FOR IPv6 ADDRESS GENERATION: SIMULATION SOFTWARE DEVELOPMENT
Author:	NASHRUL HAKIEM, MOHAMMAD UMAR SIDDIQI
Abstract:	This paper presents the development of a one-to-many reversible mapping mechanism simulation for IPv6 address generation. The aim of this mechanism is to improve IPv6 addresses generation in terms of privacy and security in an enterprise local area network (LAN). Each time a user accesses a network, a dynamic IPv6 address is assigned via the DHCPv6 server. The dynamic address (one-to-many mapping) is to protect a user from unwanted behavior analysis attempting to exploit IPv6 addresses, thus protecting user privacy. However, the dynamic address can be uniquely linked to the user (many-to-one mapping) if the need arises. The one-to-many reversible mapping is generated dynamically using Cipher Feedback (CFB) mode of operation of the Advanced Encryption Standard (AES). Software simulation is developed using the software engineering waterfall model and a Unified Modeling Language (UML) class diagram as a notation. The results show that the mechanism simulates well for IPv6 address generation and IPv6 address owner identification. The one-to-many mapping may be incorporated into DHCPv6 software and many-to-one mapping may be implemented as a complement of local area network monitoring software.

Author:	M.H. CHONG, H.JAAFAR, W.Z.W.HASAN, S.SHAFIE, M.N.HAMIDUN, M.M. ISA, A.F. HAWARY
Abstract:	Force sensor (or pressure sensor) has gained increasing interest among the researchers. Using the Microelectromechanical Systems or MEMS technology, the size of the force sensor can be miniaturized and this ignites more possible application in the field of biomedical and robotic applications. Recent researches show the application of force sensor on the prosthetic hand, an artificial limb connected to an amputated person. This paper presents on simulating the sensitivity of the thick film force sensor using IntelliSuite software. The force sensor is realized by using the piezoresistive material on the cantilever structure.There are three force sensor designs are simulated. Two of the designs are simulated using glass as substrate, and while the remaining one is of alumina substrate. The sensitivity simulated is much smaller compared to the estimations made using equations. The simulations show that the glass sensor fares better than the alumina sensor. If the substrate is the same, the sensor with the bigger dimension has better sensitivity.

Title:	MINING ROAD TRAFFIC ACCIDENT DATA TO IMPROVE SAFETY IN DUBAI
Author:	ABDELAZIZ ARAAR, AMIRA A. EL TAYEB
Abstract:	Road traffic accidents are a major public health concern, resulting in an estimated 1.2 million deaths and 50 million injuries worldwide each year. Dubai in particular experiences a high rate of such accidents. Research on road safety has been conducted for several years, yet many issues still remain undisclosed and unsolved. Specifically, the relationships between drivers' characteristics and road accidents are not fully understood. In this work, we started by collecting a dataset between 2008 and 2010 from Dubai Police. After preprocessing, we modeled the data to 19 attributes and 5 classes. We used WEKA data mining software with the 4 classifier methods (Decision trees, Rules induction, BayesNet, and MultilayerPerceptron). We applied data mining technologies to link recorded accident, driver, and road factors to accident severity in Dubai, and generated a set of rules that could be used by the Dubai Police to improve safety. Empirical results showed that the developed models could classify accidents within reasonable accuracy. The comparison of these classifiers showed that the neural networks classifier (MultilayerPerceptron algorithm) is the best classifier for all classes. We generated recommendations and conclusions.

Title:	ON THE ANALYSIS OF PARAMETERS’ EFFECT IN PDE-BASED IMAGE INPAINTING
Author:	BAHA. FERGANI, MOHAMED KHIREDDINE. KHOLLADI
Abstract:	Image Inpainting is an important task in the field of image processing, with many applications in the fields of image and vision analysis. It aims at restoring damaged or missed regions in images in the case of undetectable forms. The basic idea in image inpainting, according to the Bertalmio’s approach, is to smoothly propagate information from the boundaries of the missed region toward the inside of the gap in the direction of isophotes. The purpose of this paper is to analyze the effects of different parameters in Bertalmio’s approach on the quality of the resulting inpainted image. The parameters dealt with in the paper are the rate of improvement, the number of iterations, the number of isotropic diffusion and the number of anisotropic diffusion.

Author:	ALA ABDELALI , DRISS EL OUADGHIRI, MOHAMED ESSAAIDI
Abstract:	MPLS/VPN backbones are widely used today by various operators and private companies in the world, high to medium-sized, either use an operator or build their own MPLS/VPN backbone. Real time applications like voice and video are more and more integrated to end user applications, making them ever more time sensitive. Operators are offering services like hosting companies voice platforms, voip call centers, iptv ..etc. All these aspects make the convergence time inside a backbone a challenge for service providers. However, the global convergence time is an assembly of several factors including: link or node failure detection, IGP failure detection, LSP Generation, SPT Computation, RIB update, local FIB creation and distribution ...updates signaling...etc., a lot of approaches can be used to minimize the convergence time, our approach consist on enhancements and optimization in control and forwarding plane, the scope of our work is the core backbone, however a lot of things can also be made at the access. In this article we especially focuses on stressing and comparing two methods: “LDP over RSVP in the core P routers” and “ LDP Fastreroute in the core P routers”. Beyond the “state of the art” and implementation of both protocols, we describe in detail our design considerations, impact of faults and test results, the aim of the study is to give an accurate idea of gains and drawbacks of each method and which one more fits an operator infrastructure. We consider this work as a contribution to the global research on the “network convergence item”, it more deals with the state of the art, and features interoperability. A continuation of this work is using same approach while modeling new protocol concepts holding intrinsically the convergence as a constraint.

Title:	ANALYSIS OF VRPPIC AND PPIC FOR SISO AND SIMO MC-CDMA UPLINK SYSTEM
Author:	NOOR MOHAMMED. V, P. S. MALLICK, L. NITHYANANDAN
Abstract:	This paper presents an extended version of Partial Parallel Interference Cancellation (PPIC) called Variance reduced Partial Parallel Interference Cancellation (VRPPIC) for multicarrier code division multiple access uplink systems. The combination of PPIC receiver and new bit estimator is called VRPPIC detector. This realization is derived for the main PPIC operation and soft decision (SD) from PPIC, which are linear combination of the bit estimator using appropriate Weighting Factors (WF). These weighting factors are derived from Partial Parallel Interference Cancellation (PPIC) weighting factors. It is used to reduce the conditional variance of the final stage signal estimation. An Optimal Weighting Factor (OWF) selection algorithm has been derived for VRPPIC detector scheme, to minimize a monotonically increasing condition variance function. For all the interference cancellation stages the derived OWFs are equal and can easily be obtained from a linear function of active users. Simulation has been done in VRPPIC detector and PPIC detector using optimal weighting factors and randomly selected weighting factors. The result shows that the VRPPIC with OWFs outperforms both VRPPIC and PPIC with randomly selected weighting factors. Also it is shown in this paper that if there are multiple antennas at the receiving end, the performance of the detector is further improved. This leads to generalization that if data comes from single stream (single input) and there are multiple outputs (antennas) at the receiving end, the detector for multiple reception MC-CDMA strikingly outperforms the conventional systems with single antenna at the receiving end.

Abstract:	The rapid development of computer networks has brought great convenience to people's learning, work and life. However, because the network has the characteristics of sharing and openness, and the computer systems often use the open operating system, computer networks are more vulnerably subject to attack from hackers. The network security issues have been particularly prominent. Using of Trojan technology to attack and destroy the network system has become the greatest threat to the security of information networks. On the basis of analyzing the life characteristics, working principle and hiding technique of Trojans, the paper gives the Trojan removal method. Meanwhile, the paper proposes a K-summary clustering algorithm. The algorithm can accurately locate the Trojan position and significantly saving the positioning running time, which has certain practical significance to improve the security of the network.

Title:	AN APPROACH FOR SUPERPIXELS USING UNIFORM SEGMENTATION AND RECIPROCAL NEAREST NEIGHBORS CLUSTERING
Author:	JUNRUI LV
Abstract:	An approach using uniform segmentation and reciprocal nearest neighbors (RNN) clustering is presented to generate super pixels. The method is made of two steps. First, image is segmented to a large number of regular homogeneous small regions which are similar to cell. Second, instead of the original image pixels, small regions segmented is regarded as input of RNN clustering. Regional diversity of average value normalized and variance form the new similarity criterion. The area constraint filter limited the large size of superpixels guarantees uniformity and compactness of super pixels. Finally, some regions in a small range of distance are merged by RNN clustering. Results of experiment on BSDS 500 dataset of natural images show the proposed method has advantages of high boundary recall and low under segmentation error over SLIC super pixel on small numbers super pixels.

Author:	LEI GAO, SHULIN PAN, SHEN JIAO
Abstract:	Mathematical expressions exist in all kinds of documents. The automatic location , recognition, analysis and understanding of mathematical expressions are important. Recognition of mathematical expressions has been an attractive problem for the pattern recognition community. When we meet the mathematical expressions we can’t recognize them like the way of ordinary text recognitions. We are in urgent need of a new method to process the mathematical expressions. We should firstly recognize all the symbols which constitute the expressions and define the composite structures and constrains and relationships of all the symbols. And we also should distinguish the levels of hierarchy of every symbol and the corresponding matrices and select the feature items and set the weight numbers. Analytic hierarchy process is caught to build the expression model. First, the hierarchy model is set up. Second, pairwise comparison matrix is set up. Then, a series of computer process will be going on including computing the weight vector and consistency checking and computing combination weight vector and doing combination consistency checking and constructing the judgment matrix and computing weight vectors. Experience has proved that this is a proper method to process mathematics expressions.

Title:	RESEARCH OF COMBINATORIAL OPTIMIZATION PROBLEM BASED ON GENETIC ANT COLONY ALGORITHM
Author:	ZEYU SUN, ZHENPING LI
Abstract:	Ant colony algorithm of the traditional combinative optimization consumes a large amount of time in the process of solving the optimization, which has a tendency to partial optimization and slow convergence along with many redundant useless iterative codes and low operation efficiency. A generic optimized ant colony algorithm is thus proposed. This algorithm has the ability to fast global search of generic algorithm along with parallelism and positive feedback mechanism of ant algorithm. It determines the distribution of pheromone on the path by means of generic algorithm changing selection operators, crossover operators and mutation operators. Then ant algorithm is applied into feature selection. Supporting vector machine classifiers is used to evaluate the performance of the feedback sub-variorum.

Title:	ENERGY MANAGEMENT SCHEME WITH LOAD BALANCING FOR PREEMPTIVE DYNAMIC SOURCE ROUTING PROTOCOL FOR MANET
Author:	V.RAMESH, Dr.P.SUBBAIAH
Abstract:	Energy management issues are very important in the context of ad hoc networks. Energy needs to be optimally utilized so that the nodes can perform their functionality satisfactorily. MANETs are energy constrained as most ad hoc nodes to day operate with limited battery power. So, it is important to minimize energy consumption of the entire network in order to maximize the life time of the network. In this paper we proposed load balancing method for the new on-demand routing protocol (Preemptive DSR). As per the method, the PDSR selects a route at any time based on the minimum energy availability of the routes and the energy consumption per packet of the route at that time. The Simulation results shows that PDSR has increased packet delivery ratio and decreased delay compared with existing DSR.

Title:	TOWARDS AN EDUCATION BEHAVIORAL INTENTION MODEL FOR E-LEARNING SYSTEMS: AN EXTENSION OF UTAUT
Author:	PENG-CHUN LIN, HSIN-KE LU, SHANG-CHIA LIU
Abstract:	E-learning has continued to gain the interest of enterprises and universities. As an organization’s deployed e-learning systems grow, it is important for researchers to evaluate the performance of those systems. With the growing trend toward web-based learning systems, behavioral intention models (such as TAM, TPB, TAM2 and UTAUT) seem particularly helpful to examine whether and why people use e-learning technologies. Prior research has presented various perspectives on individual difference, which mostly focused on demographic variables, such as age, gender, education and individual experience. It is not easy to clarify the cross-effectiveness and redundancy among these demographic variables. In this study, learning and teaching styles are regarded as cognitive individual differences in adopting e-learning systems. Matching teaching and learning styles improves learning, attitudes, behavior and motivation. The proposed model, EduBIM (Education Behavioral Intention Model), focuses on the degree of correspondence between students’ perceived learning and teaching styles, which together directly moderate the intention and usage of e-learning systems. This study enriches the UTAUT model by integrating cognitive individual differences to synthesize the effects of demographic moderators. This model will enable researchers to evaluate behavioral intention toward e-learning systems and to propose further studies on system acceptance.

Title:	A MODIFIED HONEY BEE MATING OPTIMIZATION ALGORITHM FOR MULTI-OBJECTIVE VOLTAGE CONTROL OF DISTRIBUTED HYBRID WIND AND PV SYSTEMS
Author:	LIZHEN WU, XIAOHONG HAO
Abstract:	Recently, Distribute Generation sources (DGs) connected to the distribution network has received increasing attention. The daily voltage control is one of the most important schemes in distribution networks, which can be affected by DGs. This paper presents a multi-objective Voltage optimizes control modeling, including objectives that are the total cost of power generated by Wind Farms (WFs) and Photovoltaic (PV) pants and the grid; the total electrical energy losses; the total emission and the voltage deviations of the bus. Moreover, a new optimization algorithm based on Modified Honey Bee Mating Optimization (MHBMO) algorithm is proposed to determine the best operating point for the active power generated by WFs and PVs, reactive power values of capacitors. In order to overcome the shortcomings of original HBMO algorithm, the mating process is improved. During the optimization process, the proposed algorithm finds a set of non-dominated (Pareto) optimal solutions which are stored in an external memory called repository. Also a fuzzy clustering technique is used to control the size of the repository within the limits. Finally, a typical IEEE 32-bus distribution test system is used to investigate the feasibility and effectiveness of the proposed method. Simulation results illustrate the correctness and adaptability of the proposed model and the MHBMO algorithm.

Title:	AUTOMOTIVE WIMAX RADAR NETWORKS: THE FUTURE OF INTELLIGENT TRANSPORTATION SYSTEMS
Author:	NIRMALENDU BIKAS SINHA, SAMIRAN PRAMANIK, CHADAN KUMAR SARKAR, RABINDRANATH BERA
Abstract:	This paper addresses the developmental efforts towards the realization of vehicle to vehicle cooperative collision warning system for ITS. In this intelligent system either the vehicle or the infrastructure can communicate its location or other information to surrounding vehicles or nearby infrastructure for its implications in cooperative driving and vehicle safety. Commercial vehicles with radar system operating in ‘SKIN’ or ‘TRANSPONDER’ mode is used for this intelligent system. In the ‘SKIN’ mode of operation only one vehicle is associated with the radar whereas in the ‘TRANSPONDER’ mode both the vehicles will be fitted with the radar and communication system. Vehicles will be ‘friends’ to each other by integrating the local radar mounted on each vehicle with vehicular communication. The goals of this paper are twofold: Providing an engineering argument of possible functional architectures of such systems and presenting a plausible example of the proposed future-trajectory-based design, which estimates and communicates vehicle positions, predicts and processes the future trajectories for collision and decision making using WiMAX waveforms. However for real time implementation of the system, a careful selection of the latest high speed wireless technology WiMAX is to be embedded with the SKIN or TRANSPONDER mode of radar operation for safe communication purposes in order to avoid collision on road. The authors have developed automotive WiMAX radar networks for SKIN and TRANSPONDER mode utilizing the VLSI based advanced development platforms. This paper will highlight the achievements of the model to develop an intelligent transport system.

Title:	RESEARCH ON THE COMBINING OF COMPRESSED SENSING AND NETWORK CODING IN WIRELESS SENSOR NETWORK
Author:	JIPING XIONG, JIAN ZHAO, LIFENG XUAN
Abstract:	Wireless sensor networks (WSN) are faced with the problem that network size is inversely proportional to network lifetime because the number of data packets transmitted is equal to the number of communication nodes for recovering original signal. Compressed sensing(CS) compresses and samples in sparse domain of network source to reduce the amount of transmitted data to accurately reconstruct original signal which is far less than the number of network nodes, and thereby reducing total energy consumption of network. Network coding (NC) is applied to intermediate node to encode data before forwarding it rather than simply store and forward it, achieving balance of network load. This paper introduces research status of two emerging technologies, proposing combined method by researching their inner contact and applying them to WSN to expand network size while reducing energy consumption to prolong life of network. Furthermore, we conclude our work and point out future research directions.

Abstract:	Privacy preserving classification mining is one of the fast-growing subareas of data mining. The algorithm-related methods of privacy-preserving are designed for particular classification algorithm and couldn’t be used in other classification algorithms. To solve this problem, it proposes a new algorithm-irrelevant privacy protection method based on randomization. This method generates and opens a new data set that is different from the original data set independently as the perturbed data. The perturbed data and the original data have the same distribution. Users get the models of the original data from the perturbed data. Experimental results demonstrate that the classification algorithms can be used on the perturbed data directly. And this method reduces the privacy data disclosure risk more effectively.

Title:	SPOKEN DOCUMENT CLASSIFICATION BASED ON LSH
Author:	ZHANG LEI, XIE SHOUZHI, HE XUEWEN
Abstract:	We present a novel scheme of spoken document classification based on locality sensitive hash because of its ability of solving the approximate near neighbor search in high dimensional spaces. In speech-text conversion stage, although lattice can provide multi-hypothesis during speech recognition, it is too complex to extract proper word information. Confusion network is adopted to improve word recognition rate while keeping the corresponding posterior probability. In vector space model, modified tfidf on posterior probability is proposed to handle the negative effects of the words with very low posterior probability. Furthermore, after generating the indexing structure based on locality sensitive hash, 1-nearest and N-nearest schemes are adopted in classifier. To spare the execution time, fast locality sensitive hash is conducted. Experiments on the data from four kinds of video programs show the effectiveness of proposed scheme.

Title:	AN ENHANCED EARLY DETECTION METHOD FOR ALL ZERO BLOCK IN H.264
Author:	CONG-DAO HAN
Abstract:	Transformation and quantization are important steps for changing spatial residual data into frequency signal component. All-zero block (AZB) detection is an efficient means to reduce calculation times of transformation and quantization. In order to raise the efficiency of all-zero block detection and avoid error judgment, an enhanced all-zero block detection approach is proposed by using the base matrixes in this paper. Firstly, the base matrixes of integer transformation coefficients are analyzed. It can be found that all elements in the same sub-area are equal or inverse to each other. Considering this distribution property, we can deal with the elements within the same sub-area together and deduce a looser judgment criterion for all-zero block. Consequently, a larger proportion of all-zero blocks can be detected in advance. The experiments results demonstrate that the proposed algorithm outperforms other methods in the detection rate.

Abstract:	Most of the elderly have difficulties with computer technology. They lack computer literacy, and at the same time, have physiological changes that are associated with impaired perception, cognition, and other social aspects. These limitations can be lessened using multimedia elements to assist in their interaction with computers. One of these multimedia elements is 3D animation. We have incorporated 3D animation into a digital educational nutritional package, which was designed following the design guidelines for older adults, for better interface user interaction. An experiment was carried out to measure user acceptance; and a comparison was made between the digital package and a booklet. Questionnaires were distributed to six elderly subjects, aged 60 to 75 years old. Overall, the results showed that the 3D animation was helpful in facilitating an understanding of the content. The comparison experiment involved ten respondents that were divided into the experiment (digital package) and control (booklet) groups. Each group was given a task and the completion time for each was recorded. The findings indicate that the content exploration using the digital package was faster than using the traditional booklet. Of the respondents, 60% from the experiment group were able to access the content in less than two minutes; compared to 40% from the control group. These initial findings indicate the possibility of using a digital education package, and as such, should be explored further with larger samples and modules, in order to increase the nutritional and health knowledge and awareness among the elderly.

Title:	HYBRIDIZING RELIEF, MRMR FILTERS AND GA WRAPPER APPROACHES FOR GENE SELECTION
Author:	SALAM SALAMEH SHREEM, SALWANI ABDULLAH, MOHD ZAKREE AHMAD NAZRI, MALEK ALZAQEBAH
Abstract:	Gene expression data comprises a huge number of genes but have only few samples that can be used to address supervised classification problems. This paper is aimed at identifying a small set of genes, to efficiently distinguish various types of biological sample; hence we have proposed a three-stage of gene selection algorithm for genomic data. The proposed approach combines ReliefF, mRMR (Minimum Redundancy Maximum Relevance) and GA (Genetic Algorithm) coded as (R-m-GA). In the first stage, the candidate gene set is identified by applying the ReliefF. While, the second minimizes the redundancy with the help of mRMR method, which facilitates the selection of effectual gene subset from the candidate set. In the third stage, GA with classifier (used as a fitness function by the GA) is applied to choose the most discriminating genes. The proposed method is validated on the tumor datasets such as: CNS, DLBCL and Prostate cancer, using IB1 classifier. The comparative analysis of the R-m-GA against GA and ReliefF-GA has revealed that the proposed method is capable of finding the smallest gene subset that offers the highest classification accuracy.

Title:	ANALYSIS OF DIFFERENT ACTIVATION FUNCTIONS USING BACK PROPAGATION NEURAL NETWORKS
Author:	P.SIBI, S.ALLWYN JONES, P.SIDDARTH
Abstract:	The Back propagation algorithm allows multilayer feed forward neural networks to learn input/output mappings from training samples. Back propagation networks adapt itself to learn the relationship between the set of example patterns, and could be able to apply the same relationship to new input patterns. The network should be able to focus on the features of an arbitrary input. The activation function is used to transform the activation level of a unit (neuron) into an output signal. There are a number of common activation functions in use with artificial neural networks (ANN). Our paper aims to perform analysis of the different activation functions and provide a benchmark of it. The purpose is to figure out the optimal activation function for a problem.

Title:	ANTENNA EFFECTS ON PHASED ARRAY MIMO RADAR FOR TARGET TRACKING
Author:	SAMIRAN PRAMANIK, NIRMALENDU BIKAS SINHA, CHADAN KUMAR SARKAR
Abstract:	Multiple-input multiple-output (MIMO) radar can achieve improved localization performance by employing a coherent processing approach with proper antenna positioning. Coherent processing, however, entails the challenge of ensuring phase coherence of the carrier signals from different distributed radar elements. In recent years, studies have shown how the performances of conventional phased-array radar can be improved by using the same approach. In this work, we aim to address such a challenge by providing a systematic treatment of the phase synchronization problem in coherent MIMO radar systems. We propose and study in coherent MIMO radar and phase array radar with coherent beam for the effectiveness of the above problems. The results show that at high and low SNR values phase array radar with coherent beam provides great improvements of target detection performance over coherent MIMO radar. Simulation results are presented to validate our theoretical analysis.

Title:	PROBABILITY DETECTION FOR STATISTICAL MIMO RADAR: ALGORITHMS AND THEIR ANALYSIS
Author:	SAMIRAN PRAMANIK, NIRMALENDU BIKAS SINHA, CHADAN KUMAR SARKAR
Abstract:	Multiple-input–multiple-output (MIMO) radar is an emerging technology that has significant potential for advancing the state-of-the-art of modern radar. This is a multiple antenna radar system capable of transmitting arbitrary waveform from each antenna element. Like MIMO communications, MIMO radar offers a new paradigm for signal processing research. It’s significant potentials for fading mitigation, resolution enhancement, and interference and jamming suppression, which can result in significantly improved target detection, parameter estimation, target tracking and recognition performance. To identify a target in statistical MIMO radar system multiple antennas, not closely placed, for transmission and reception is used. This paper introduces the signal processing issued in statistical MIMO radar and coherent MIMO radar for improved target detection and recognition performance. The fundamental difference between statistical MIMO and other radar array systems is that the latter seek to maximize the coherent processing gain, while the former capitalizes on the diversity of target scattering to improve radar performance. Compared to coherent MIMO radar, statistical MIMO radar can offer better parameter identification , higher resolution which allows for much flexibility for transmit beam-pattern design and waveform optimization. This paper focuses on the application of the target spatial diversity to improve detection performance. The optimal detector in the Neyman-Pearson sense is developed and analyzed for the statistical MIMO radar in case of stationary target. The performance improvement achieved by the use of angular diversity in statistical MIMO radar is investigated. The results show that at high and low SNR values statistical MIMO radar provides great improvements of target detection performance over coherent MIMO radar. Finally, a number of numerical examples demonstrated for the effectiveness of the proposed approaches. Therefore, statistical MIMO radar can be applied to enhance radar resolution by allowing the measurement of one scatter at a time.
