Sensor Management with Regional Statistics for the PHD Filter

This paper investigates a sensor management scheme that aims at minimising the regional variance in the number of objects present in regions of interest whilst performing multi-target filtering with the PHD filter. The experiments are conducted in a simulated environment with groups of targets moving through a scene in order to inspect the behaviour of the manager. The results demonstrate that computing the variance in the number of objects in different regions provides a viable means of increasing situational awareness where complete coverage is not possible. A discussion follows, highlighting the limitations of the PHD filter and discussing the applicability of the proposed method to alternative available approaches in multi-object filtering.
