摘　　要：目前的多目标跟踪仿真系统为实现更高的跟踪精度和跟踪效能,多采用复杂的先进跟踪算法进行建模仿真,且仿真环境设置较为理想,不利于工程实践和系统仿真,其工程应用价值大打折扣。针对上述问题,采用连续系统的建模仿真方法,根据当前空战飞行器编队作战的发展对地面武器跟踪制导系统的新要求,提出并设计了基于M ATLAB的相控阵雷达机动多目标跟踪仿真系统,以KALM AN滤波算法为主线,对多目标数据互联、机动检测与辨识以及目标编批和航迹处理等核心模型的算法、关键技术进行了深入研究,开发了与KALM AN滤波算法较为匹配的跟踪滤波系统,最后以跟踪空中多目标编队飞行为例,对仿真系统进行了模型校验与测试。仿真结果验证了模型和方法的有效性,可为系统跟踪效能的分析评估提供平台和依据,对于相控阵雷达系统的开发和战术使用具有积极意义。The current Multiple Target Tracking simulate system often model by advanced tracking estimation,and the simulation condition is usually ideal,which went against project practice and system simulation,watered its project application down.Aiming at above problems,adopting signal simulation,considering current development of airfight craft group battle and the request of ground weapon tracking and homing system,the battle simulation system of Multiple Maneuvering Target Tracking of Phased-Array Radar is presented based on MATLAB.And the key Estimation and technique of data association,maneuver check,target group and tracks associationare studied,form one tracking system suited with Kalman filter Estimation.Simulation is carried out whose result verifies the efficiency with one Multiple Maneuvering Target case.The successful exploitation of the system will supply the analyses evaluation of tracking efficiency with performance and basis,which has active sense for the system exploitation and tactics use of Phased-Array radar.
