基于IMM的三维机动目标跟踪算法研究

Research on 3D Maneuvering Target Tracking Based on IMM Algorithm

对单站雷达三维空间机动目标的跟踪方法进行了研究,选取匀速运动模型分别组合"当前"统计模型和Singer模型的两种交互多模型跟踪滤波算法来处理三维空间机动目标测量数据并进行仿真分析,仿真结果表明,IMM算法的滤波结果优于单模型滤波,验证了算法对机动目标的跟踪有效性。

The target tracking problems of the monostatic radar in the 313 space are studied in this paper. It respectively combines constant velocity （CV） model with ＂current＂ statistical model or Singer model in order to form a new Interacting Multiple Model（IMM） tracking algorithm. Then, it utilizes IMM algorithms to process the measurement data of 3D maneuvering target and to analyze the simula- tions. Simulation results show that filtering effect of IMM algorithms is apparently better than that of single models,and verify the tracking effectiveness of the algorithms.
