| Abstract | The knowledge on the radar cross section (RCS) of a ground target can support classification and identification tasks. In addition, it might also contribute to the resource management of the radar system because in general less energy needs to be emitted towards larger targets in order to obtain a detectable target return compared to small targets. The focus of this work, however, is to distinguish closely-spaced targets by first determining the mean RCS of the individual moving objects and then using this additional target attribute information to improve the track continuity in such a challenging environment. The RCS of a ground moving target can be estimated based on signal strength measurements. For this method to work, the RCS fluctuations are assumed to follow the analytically tractable Swerling-I and Swerling-III cases. The estimation scheme of the target RCS is incorporated into the Gaussian mixture variants of the probability hypothesis density (PHD) and cardinalized probability hypothesis density (CPHD) filters. The performance of these algorithms is analyzed based on a multi-target simulation scenario using a modified version of the optimal subpattern assignment (OSPA) metric that also accounts for labeling errors. |

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.
