Multi-Target Tracking with Partially Unresolved Measurements

The problem of limited sensor resolution, although usually ignored in targettracking, occurs in multi-target scenarios whenever the target distance falls below thesize of the sensor resolution cell. Typical examples are the surveillance of aircraft information, and convoy tracking for ground surveillance. Ignoring the limited sensorresolution in a tracking system may lead to degraded tracking performance, in particularunwanted track-losses. In this paper, an extension of the resolution model byKoch and van Keuk to the case of arbitrary object numbers is discussed. The model isincorporated into the Joint Probabilistic Data Association Filter (JPDAF) and appliedto a simulated scenario with partially unresolved targets
