Abstract | The abundant space, time, frequency and code resources of distributed multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) enables it to bring various applications. The generalised ambiguity function (GAF) of distributed MIMO SAR is analysed. By equating the bistatic SAR to equivalent phase centre (EPC), the GAF can be expressed as sum of that of mostatic SAR. The influence of EPC's position on GAF is analysed, including its effects on amplitude items in range direction, in azimuth direction and phase item, and the boundary conditions of formation scale within which the envelope items are not affected are deduced. Furthermore, the phase in GAF is expressed as linear combinations of EPC position related to formation centre. The simulation results verify the negligibility of formation scale and show that the linear combination expression is accurate enough to evaluate the resolution. |

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.
