PHD Filter for Multitarget Tracking with Range Ambiguity

Abstract:

It is difficult to track multitarget of which the number is unknown and time varying, especially with range ambiguity. The probability hypothesis density (PHD) filter propagates the first order moment of the posterior multitarget density, from which the number of targets as well as their individual states can be extracted. However, when tracking multiple targets via the middle or high pulse repetition frequency (PRF) radar, the problem of range ambiguity has to be solved. In this paper, a novel method for joint range ambiguity resolving and multitarget tracking is proposed. The feasibility and effectiveness of the proposed method are verified by simulation results.
