| Abstract | The geosynchronous synthetic aperture radar (GEO SAR) echo simulation has an important significance for GEO SAR system design and image algorithm verification. The study discusses the main steps of the GEO SAR echo simulation process and the calculation of key parameters. At the same time, because GEO SAR has a high orbital altitude and a long-time delay, the error caused by the ‘go-stop-go’ hypothesis must be taken into account. For this reason, the authors have studied the slant range iterative model without the assumption. It is used to calculate the distance between the satellite and target in the echo simulation. Experimental results show that the method is effective and feasible. Based on this, the space variant characteristics of GEO SAR are analysed in detail. It can be seen that the echo signals do not satisfy the range and azimuth invariance. |

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.
