Performance of a multiscan track-to-track association technique

The formula for calculating the theoretical probability of false association for the technique of track-to-track association (TTTA) using multiscan data is presented. The multiscan TTTA technique and the single-scan TTTA technique are studied by analysis and simulation. The conclusion is that the theoretical performance of the multiscan method is better than that of the single-scan method; however the practical performance of the former evaluated in our simulation is much worse than its theoretical performance, yet could still be more or less better than that of the latter. The reason is that estimation errors of the sensor-level tracks are strongly dependent across time.
