A target tracking method based on tangential and normal acceleration variable-structure multiple model

Considered the maneuvering target motion characteristics, a motion model according to the decomposition of the acceleration is investigated. Compared with traditional model set, this model complies with the need of variable-structure multiple model (VSMM) to model set. In this paper, we present a tangential and normal acceleration VSMM target tracking algorithm with the advantage of active digraph switching algorithm. Simulation results show that the performance of the algorithm is better than that of traditional IMM algorithm.
