Radar Target Tracking Based on Interactive Multi-model Cubature Kalman Filter

Aiming at the difficulty of model construction in the process of nonlinear maneuvering target tracking, the interactive multi-model algorithm based on CV and CT models is studied. Combined, an interactive multi-model cubature Kalman filter algorithm, which can be applied to the radar’s need for air maneuvering target tracking, is designed. The simulation results show that compared with the single model CKF and IMM-UKF, the IMM-CKF has higher tracking accuracy and stronger model adaptability, and has important engineering application value.
