| Abstract | Three-dimensional (3D) imaging of a moving target can be achieved via a wideband multiple-input multiple-output (MIMO) radar with planar array in a single snapshot. The sparse recovery (SR) method has been introduced to deal with the MIMO imaging problem with sparse array recently. For sparse linear array, SR method can successfully achieve the high cross-range resolution. For sparse planar array, however, it is not effective to use a SR algorithm directly in 2D cross-range direction, because the final 2D imagery will be blurred by the SR-induced range cell migration (RCM) in the former cross-range direction. To remove the RCM, a joint sparsity-driven method is proposed in this study by exploiting the joint sparsity of echo signal. An improved imagery can be obtained with fewer antennas and higher calculation efficiency. Comparative experiments demonstrate the superiority of the proposed method. |

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.
