Abstract:

A variable structure interactive multiple model filtering and smoothing algorithm is proposed for maneuvering target tracking. Firstly, the filtering and smoothing problems are described briefly, and the mathematical models of forward interactive multiple model filtering and backward interactive multiple model smoothing are given. Then, a new accurate model of the variable-structure interactive multiple model algorithm is established. The model subsets run independently in parallel, and the state estimation of the model subset with the highest probability is selected as the final estimation result. Finally, the filtering data of the variable structure interactive multiple model algorithm is smoothed, and the variable structure interactive multiple model filtering and smoothing algorithm is obtained, which further improves the target tracking accuracy due to the combination of forward filtering and backward smoothing. Simulation results show that the tracking performance of the variable-structure interactive multiple model filtering and smoothing algorithm is better than other methods.

Key words: variable structure interactive multiple model, maneuvering target tracking, filtering, smoothing
