Tracking in multi sensor multi target (klSMT) scenario is a complex problem due to the uncertainties in the origin of observations. Solution to this problem requires appropriate gating and data association procedures to associate measurements with targets. A PC MATLAB program has been developed based on gating and data association using nearest neighborhood approach to track multiple targets with multiple ground based radars. In this paper the details of the procedure followed and tbe results of the performance of the algorithm for a typical (MSMT) situation are presented.
