Abstract | Based on digital radio frequency memory technology, jammers can copy the radar signal multiple times by different time delay and frequency shift to form deceptive multiple false targets. For non-self-defensive-type main lobe jamming, the jamming signal and the real signal from different angles into the radar receiver, when the false target generated by the jammer was in the same range cell as the real target, the angle measurement result was with high probability in the energy centre between the target and jamming. Thus, the angle tracking performance of the monopulse radar was retrograded. In this study, an anti-jamming method called angle inversion based on power synthesis is proposed to effectively estimate the real perspective of the target from deceptive multiple false targets, and the anti-jamming performance is revealed under the condition of a different jammer-to-signal ratio. |

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.
