To solve the real-time and reliability problem the features of under maneuver target motion, namely, of the underwater maneuver target tracking, according to slow speed and weak motion capability, the mixing filter between pattern space and measurement space is performed by the wavelet transform, and the algorithm of multirate interacting multiple model is proposed for under maneuver target tracking. Meanwhile, the uniform expressions of multirate interacting multiple model are presented. The simulation results show that the algorithm of the multirate interacting multiple model has the low computation complexity and can improve the real-time and reliability performances of the underwater maneuver target tracking.
