Abstract

Considering the characteristics of underwater passive target tracking, the technology of multisensor state estimation in bearings-only underwater distributed system is studied in this paper in order to improve tracking performance. According to feedback mechanism in radar systems, state estimation based on multisensor´s bearing sequences is fused on condition that observation platform makes efficient maneuvers. The simulation results show that the track fusion can not only complete the slate estimation but also greatly improve the tracking performance of local sensors by using feedback mechanism. It offers reference to underwater passive target tracking.
