Abstract :
Considers the effects on track association of two features that are often neglected in analysis. These two features are the cross-covariance between two tracks of the same target and the effects of a loss of resolution in a sensor. The sensors modelled in this paper are nonhomogeneous in both the state space and the measurement space, and a method for calculating the cross-covariance for such dissimilar sensors is derived. Also, a simple resolution model is proposed. The paper uses Monte Carlo simulations to illustrate the effects of these two features on a number of track association methods.
