摘　　要：针对中段弹道目标群运动时的真假目标识别问题,提出一种基于轨迹特性的弹道目标识别方法。该方法通过雷达观测数据还原出弹道目标运动轨迹,根据轨迹交点个数判断诱饵是单次还是多次释放模式,分别提出基于弹道参数和权值交点的识别途径,结合雷达观测弹道目标数目,归纳了基于轨迹特性中段弹道目标综合识别策略。仿真实验表明该方法的正确性并分析了雷达测量误差及布站位置等因素对识别结果的影响。A method for discrimination of midcourse target based on trajectory characteristics is proposed in this paper to recognize motion characteristics of target cluster consisting of warhead and decoys. Radar measure data are used to recover ballistic trajectory. Trajectory characteristics are used to judge the number of intersection points, and single or multiple decoys releasing process can be determined. According to different release processes, recognition methods based on trajectory parameters and weight of intersection are proposed respectively. Then, an integrated midcourse target discrimination strategy based on trajectory characteristics is developed in combination with the number of targets. Numerical simulations have demonstrated the effectiveness of the proposed approach. Some factors such as radar measurement error and radar station location are also considered as the influencing factors in analyzing recognition results.
