Paper Abstract

In recent years the problem of multiple target tracking has bene studied more and more extensively. However, as the foremost difficulties which multiple target tracking (MTT) involves, the problems of gating and track initiation have been ignored to a certain extent. Now rectangular and ellipsoidal gating are used in most MTT systems. This paper describes rectangular and ellipsoidal gating were not very successful in many cases. Then the new track gate, quasi-drip-shaped (QDS) gate, is proposed to eliminate unlikely observation-to-track pairings more effectively and to operate a pre-correlation when more than one returns are within the track gate. The sensor errors and the influence of maneuver are considered synthetically. Based on the more accurate analysis of error data distribution, QDS gate is formed. Simulation results are presented for five approximately equals ten targets include several heavily interfering ones; these illustrated the improvements obtained by using QDS gate.
