Abstract | In general, conventional synthetic aperture radar (SAR) imaging algorithms focus SAR images for stationary targets. However, in the case of moving targets, the motion of the targets induces an undesired range variation which makes the obtained SAR images to be dislocated and defocused. Therefore, in this study, the authors propose a method that effectively focuses the SAR images for the moving targets and estimates their motion parameters with single-channel SAR system. The proposed method consists of the following three steps: (i) direct exploitation of the range variation from the echo signal, (ii) range cell migration compensation with the estimated range information, and (iii) Doppler compensation and parameter estimation. The simulation results demonstrate the robust performance and high computational efficiency compared to the conventional moving target imaging algorithms. |

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.
