Controlling Track Coalescence Using Improved JPDA Filter

In this paper a modified JPDA algorithm to avoid track coalescence is proposed. An exclusive measurement is defined for every target in the new algorithm, and with other targets will be pruned, which resists two or more targets share the same measurement as a key measurement and avoids track coalescence. The simulation results show that the new algorithm can effectively solve track coalescence problem in all kinds of scenarios, while keeping a high tracking performance.
