| Abstract | A conventional dynamic target tracking algorithm can be divided into two steps. A previous estimate is propagated to current scan by using pre-designed dynamic model in the prediction step and the predicted estimate is corrected by using the current measurement in the update step sequentially. To reduce the prediction errors, one has to carefully choose the dynamic model carefully. However, exact target dynamic model is rarely known a priori. Multiple models filters which use several dynamic models present a solution. Interacting Multiple Models (IMM) filter calculates the state estimates and model probabilities for each model. In the interacting step of the IMM filter, the model estimates are mixed using the model transition matrix and the model probabilities. The elements of the model transition matrix are usually constant. This can cause performance degradation for target tracking with variable sampling periods or asynchronous multi sensor systems. We propose an adaptive model transition matrix which adjusts its elements based on variable time interval. |

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.
