Abstract | Considering the fact that target tracking of the sky wave Over-The-Horizon Radar (OTHR) inevitably faces the problems of multipath, low detection probabilities et al., we make use of the advantage of avoiding data association and low computational cost for Gaussian mixture probability hypothesis density (GM-PHD) filter and propose a multipath GM-PHD (MP-GM-PHD) filter framework. Such framework is expected to avoid the target number over-estimation problem by partitioning the radar measurement into sub-measurement set as a PHD updating cell, process the nonlinear problem with utilizing the third-degree spherical-radial cubature rule, and improve the probability of capture for missed targets by supplementing the Gaussian terms from history track information. Simulation results show that under the conditions of different detection probability, the MP-GM-PHD filter can gain a more accurate estimate of the target state and target number, capture the missed targets timely, and alleviate the problems of target number over-estimation and high computational cost by the direct use of GM-PHD filter. |

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.
