| Abstract | The use of passive radar for detection of targets of different type has gained considerable popularity in past few years. This radar uses the so-called the ”signals of the opportunities” which are already in the environment. These opportunistic signals can be of different types, both in terms of frequency and modulation type. Therefore, instead of designing a separate hardware receiving system, a better approach will be design a single software defined receiver having capability to capture any signal of interest by just changing antenna system. Also to obtain various signals of interests, a multi-channel receiver system is desired so that advance array processing algorithms like digital beamforming can be utilized. Therefore , a state of the art software defined, multi-band, and a multi-channel passive radar system has been designed and being tested. One important step in the processing of signals for final target detection is the cancelation of direct path signal coming from main transmitter. Usually this is done by a combination of digital beamforming and adaptive filters based interference cancelation algorithms. An improved digital beamformer is designed with complete control of side-lobes to suppress the direct path signal. Also improved interference cancelation is done by using a cascade (two-stage) of adaptive filters. By using the combination of these techniques it will be shown that a considerable weak target can be detected. |

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.
