Abstract | MIMO techniques have been well studied for communications applications where they offer benefits in multi-path fading environments. This terminology is now appearing in the radar literature, but in several forms causing some confusion. Much of the existing work has focused on multistatic radars with sufficient spatial separation to de-correlate target RCS fluctuations, and where the data from the radars are combined incoherently. Another form of MIMO radar, closer to the communications technique, is where multiple orthogonal signals from the individual transmitter elements of a phased array are coherently combined on reception to form multiple beams. This paper presents a simple understanding of this within-aperture MIMO technique. We show how a filled array of "phantom" elements can be formed from relatively few physical elements. We explain the phantom element concept and extend it to the synthesis of various antenna array configurations, covering one, two and three dimensional geometries. The paper describes a range of waveform and signal processing options and discusses the implications of these radar capabilities |

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.
