摘　　要：针对战斗机与导弹分离过程中产生的碎片目标易导致目标点迹断续,地面雷达难以稳定维持航迹的问题,提出基于PD模式的高速率跟踪模式及时发现分离时的目标,利用运动特征、RCS特征等信息解决机弹分离后的分类识别问题,采用改进JPDA的目标关联和多模型滤波算法解决机弹分离后的跟踪问题。During the fighter-missile separation procedure,debris targets easily result in the discontinuity of plots and the instability of tracking for ground radars.Given this,a PD-based high-rate tracking mode is proposed to recognize the targets in time,and motion and RCS features are utilized for target classification and recognition after the separation.The target correlation of the modified JPDA and the multi-model filter algorithm are adopted for target tracking after the fighter-missile separation.
