| Abstract | It is known that using two passive sensors that provide bearings-only information cannot eliminate false intersections in a multi-target environment, and results in ghost tracks. In this paper, we propose a tracking/fusion and deghosting method using two stationary acoustic sensors. The existing approaches for bearings-only information require the number of sensors to be greater than or equal to three. The method proposed in this paper makes target tracking possible in a two-sensor system through making use of frequency information. This method generates tentative tracks from all possible bearing track combinations, and distinguishes target tracks from ghost tracks using a 2-D assignment algorithm. Tentative tracks are initiated using an iterated Least Squares (LS) algorithm, and updated by an Unscented Kalman Filter (UKF) based on Doppler-Bearing Tracking (DBT) approach. The likelihood ratios of tentative tracks, which are computed based on track innovation probability density functions, are assigned as costs in the 2-D assignment algorithm. Simulation tests have been conducted to validate the effectiveness of the proposed method. |

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.
