    Abstract

    Tracking in multi-sensor multi-amp;at@ (MSMT) scenario is a complex and difficult task due to the uncertainties in origin of observations. This requires appropriate gating and data association procedures to associate measurements with target. A PC MATlAB program, based on track-oriented approach, is evaluated which uses Nearest Neigbbour Kalman Filter (NNKF) and Probabilistic Data Association Filter (PDAF)for tracking multiple targets from data amp; multiple sensors. For track-to-track fusion state vector fusion philosophy is employed. The tracking performance in presence of simulated track/data loss and recovery as well as clutter is evaluated. During the data loss , the PDAF performed better than the the NKAF. In the presence of mild clutter and spare target scenarios, the NNKF and the PDAF give similar performance.
