An IMM maneuvering target tracking algorithm based on amended model probability

A new maneuvering targets tracking algorithm FIMM is presented based on the IMM algorithm. The algorithm smooth the updated probaility of the IMM algorithm by the median filter,and then use the fuzzy inference system for real—time amendment,the result of which is as the final output weights.The FIMM algorithm increases the probability of a useful model,decreases the compe-tition between models,and improves the tracking accuracy.Simulation results show that the FIMM algorithm proposed in this article significantly inproves the tracking performance of IMM algorithm.
