| Abstract | In this paper, we consider the problem of applying compressed sensing (CS) theory to angle estimation for noncircular sources in monostatic multiple-input multiple output (MIMO) radar, and propose an angle estimation algorithm based on extended matrix compressed sensing. Firstly, a reduced-dimensional matrix is employed to transform the data matrix into a low dimensional one. Then the properties of noncircular signals are utilized to construct an extended matrix from the received data. Finally, the dictionary can be conducted to apply Orthogonal Matching Pursuit (OMP) for angle estimation. The angle estimation performance of the proposed algorithm is better than that of estimation of signal parameters via rotational invariance techniques (ESPRIT) algorithm and reduced-dimension ESPRIT (RD-ESPRIT) algorithm, and the proposed method requires no knowledge of the noise. The simulation results verify the effectiveness of the algorithm. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
