Abstract | A method of radar small/mini target wavelet transform and principal component analysis in strong clutter environment is suggested. Focusing on the situation that the small/mini target in the strong clutter environment is swamped by clutter, traditional constant false-alarm detection method limited by theory limit cannot effectively detect target, the transform domain, wavelet coefficient and principal component decomposition can realise the separation of radar small/mini target signal from the clutter signal, so as to achieve clutter suppression and small/mini target detection. The test shows the radar small/mini target detection based on wavelet transform is limited by wavelet function, decomposition layers and adaptive threshold; principal component decomposition can adapt to the signal of different radar systems, and types with good adaptability to algorithm can effectively suppress clutter and improve average signal-to-noise ratio by 7 dB. |

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.
