FUZZY-CONTROL-BASED PARTICLE FILTER FOR MANEUVERING TARGET TRACKING

Abstract

In this paper, we propose a novel fuzzy-control-based particle filter (FCPF) for maneuvering target tracking, which combines the advantages of standard particle filter (SPF) and multiple model particle filter (MMPF).That is, the SPF is adopted during non-maneuvering movement while the MMPF is adopted during maneuvering movement.The key point of the FCPF is to use a fuzzy controller, which could imitate the thoughts of human beings in some degree, to detect the target's maneuver and use a backward correction sub-algorithm to alleviate the performance degradation of MMPF caused by detection delay.Simulation results indicate that the proposed algorithm has a much better tracking accuracy than the SPF while keeps approximately equal computational complexity.Compared with MMPF, both algorithms have no tracking lost, but the tracking accuracy of the proposed FCPF is a little better than the MMPF, and the FCPF consumes about 66% computation time of the MMPF.Thus, the proposed algorithm offers a more effective way for maneuvering target tracking.
