| Abstract | By exploiting the sparsity and data structure of the received signals of airborne radar, the two-dimensional (2D) signal sparse representation (SR) model that is suitable for moving targets parameters estimation after clutter suppression is built. A novel 2D orthogonal matching pursuit (OMP) algorithm is also proposed to solve the 2D SR problem directly. The spatial parameters and temporal parameters of targets are first estimated separately based on two subdictionaries, i.e. space dictionary and time dictionary. The joint space–time parameter of each target is then obtained based on a very small space–time dictionary. The numerical results indicate that the proposed algorithm can achieve closely approximate parameters estimation performance with significant computational saving compared with the one-dimension (1D) method using traditional 1D OMP 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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
