| Abstract | Space debris of size less than 10 cm in the Low Earth Orbit (LEO) present a growing collision threat to operational space craft due to their high speed of travel (up to 8 km/s). Collision avoidance manoeuvres are currently being performed as a prevention measure. Such manoeuvres are expensive and requires prior knowledge of the incoming debris. There are some instrumemnts that have performed small space debris detection and tracking, however most of the information obtained is from space debris models. The use of available radio telescope receivers in a radar system that performs space debris detection and monitoring is becoming popular. Most radio telescopes have large apertures (high gain) and low noise temperature, so have the potential to be sensitive radar receivers. In this paper, we discuss the feasibility test results of one of the Square Kilometre Array precursors, KAT-7 for space debris detection. Using the SIMO radar equation, the L-band KAT-7 radar system is able to detect debris with a radar cross section (RCS) of 10.5 dBsm up to a maximum range of 800 km with a signal to noise ratio (SNR) of approximately 35 dB and a range resolution of approximately 0.6 m. |

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.
