| Abstract | Radiometric Accuracy of SAR Image is one of the most important requirements for KOMPSAT (Korea Multi-Purpose SATellite)-5 and it is the main objective of calibration and validation procedure. The radiometric calibration can be divided into relative and absolute radiometric calibration. Point targets whose RCS (Radar Cross Section) can be evaluated with the close-form equation are required to perform absolute radiometric calibration. CR (Corner Reflector) is the most well-known reference ground target, because it has significantly large RCS compared to backscattering coefficient of background and it is easy to evaluate the RCS from its geometrical shape. In addition, background level of CR is also important factor for absolute radiometric calibration, because high signal-to-clutter ratio is determined from not only high RCS level of a point target but also low background level. The measured RCS of the CR and analysis background level of Mongolian site are shown in the paper, in order to represent that RCS of the CR is very accurate and background level of Mongolian site is significantly low for the KOMPSAT-5 calibration |

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.
