Abstract:

This report examines an alternative assignment model for Probabilistic Multi-Hypothesis Tracking PMHT in which targets are assigned to measurements, in contrast to the original PMHT model in which measurements are assigned to targets. A new target-centric PMHT algorithm is derived and compared to its original measurement-centric counterpart. The relationship between target-centric PMHT and the probabilistic data association PDA filter for single-target tracking in clutter was examined, and a PDA-style approximation to the target state covariance matrices for target-centric PMHT is proposed. A target-centricmeasurement-centric PMHT hybrid is also proposed to address algorithm performance in the case of closely spaced targets.
