A variable-structure IMM filtering algorithm based on current statistical model

A new variable-structure IMM method for maneuvering target tracking using current statistical model is presented. The maximum acceleration - a design parameter in current statistical model, is used to design various motion models. The model set adaptation logic according to the maximum acceleration variety is also proposed in the paper. Simulation shows that the performance of new method is superior to the fixed structure IMM algorithm when target maneuver is intense.
