An Improved Interacting Multiple Model Algorithm Based on Switching of AR Model Set

To solve the problem of complex maneuvering target tracking, an improved interacting multiple model (IS-AR-IMM) algorithm based on AR model set switching is proposed in this paper. The algorithm is proposed on the basis of the AR-IMM algorithm based on AR model and S-IMM algorithm based on model set switching. Simulation shows that IS-AR-IMM algorithm not only solves the problem of increasing computational complexity and model selection caused by the increase of models in AR-IMM and S-IMM algorithms, but also has better tracking performance.
