Performance evaluation of a cascaded logic for track formation in clutter

摘要

The authors present a Markov-chain-based performance evaluation technique for two-stage sliding-window cascaded logic (2/2*m) for track formation in a cluttered environment. The main features of this technique are that it avoids the need for extensive simulations and it is more realistic than previous methods, accounting for the association gate size variation. The gates are obtained from a Kalman filter and fully account for the transient observed for the cascaded logic following the two-point initiation from its first stage. Numerical examples of performance evaluation are given along with a logic design example.
