Abstract | This is the first investigation on converse beam cross sliding spotlight SAR (CBC sliding spotlight SAR) which was firstly proposed in this essay. In conventional sliding spotlight SAR, the azimuth scene extension is larger than that of a pure spotlight mode and the azimuth resolution of scatterers is higher than in classical stripmap mode. The geometry and properties of classical standard and inverse sliding spotlight SAR were reviewed and a novel operation mode called converse beam cross sliding spotlight SAR was proposed in this essay. It's imaging geometry and properties were detailed investigated and a unified sliding factor was deduced, both classical sliding spotlight SAR and CBC sliding spotlight SAR can be realized by choosing a proper sliding factor. Simulations were executed and the point spread functions were gained. All results proved that CBC sliding spotlight SAR can gain images with azimuth resolution higher than stripmap SAR, azimuth scene extension larger than pure spotlight SAR and it plays an important complementary function in completing the operation mode of SAR. |

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.
