Hankel Matrix Rank as Indicator of Ghost in Bearing-Only Tracking

摘要

Usually, bearing angle measurements are employed in triangulation methods to display the position of targets. However, in multiradar and multitarget scenarios, triangulation approaches bring out ghosts that operate like real targets. This paper proposes a target/ghost classifier that relies on the fact that the trajectory of a ghost is actually a function of trajectories of at least two targets and therefore, the complexity of a ghost trajectory is “greater” than the complexity of targets’ trajectories.
