Data Association and Track Management in Multitarget Tracking

There are two drawbacks in the conventional multitarget association algorithm JPDA : large computation cost and lacking the logic for the track's initiation and termination in the framework.The paper develops a track management schedule,which includes several association algorithms in different circumstances.In addition,an improved fast association algorithm MPDA is proposed,which considers the effect of public measurements to the trajectories' update.MPDA can approach the association performance of JPDA with the computation cost as much as PDAF.The simulation results show that the proposed method can maintain high tracking success ratio in complicated circumstance.
