The track repulsion effect induces track swapping in difficult target-crossing scenarios. This paper provides a simple analytical model for the probability of successful tracking in this setting. The model provides a means to quantify the degree-of-difficulty in target-crossing scenarios. We analyze model-based performance predictions for a range of scenario parameters. Additionally, we provide simulation results with a multi-hypothesis tracker that confirm the increased performance challenge in crossing target settings as the ambiguity persists longer, i.e. as the targets cross more slowly.
