Abstract The performance of an association algorithm for tracks generated by radar and IR, sensors in terms of the probability of correct and false association is analytically evaluated. The closed form of correct association probability versus the decision threshold and the polynomial formulation of the decision threshold versus the correct association probability are derived; the closed form of false association probability for a fixed value of correct association probability is obtained; and the closed formulation of correct association probability for prescribed false association probability is also given. The derived closed formula can be easily applied to the performance evaluation of radar and IR track association and the design of radar-and-IR data fusion system.
