Multi-Target Tracking with Partially Unresolved Measurements
Daniel Svensson, Martin Ulmke, Lars G. Danielsson · 2010
Abstract: The problem of limited sensor resolution, although usually ignored in target tracking, occurs in multi-target scenarios whenever the target distance falls below the size of the sensor resolution cell. Typical examples are the surveillance of aircraft in formation, and convoy tracking for ground surveillance. Ignoring the limited sensor resolution in atracking system may lead to degraded tracking performance, in particular unwanted track-losses. In this paper, anextension of the resolution model by Koch and vanKeuk to the case of arbitrary object numbers is discussed. The model is incorporated into the Joint Probabilistic Data Association Filter (JPDAF) and applied to asimulated scenario with partially unresolved targets. 1
