| 摘 要： | 文章针对弹道导弹预警系统目标识别任务的特点,通过分析弹道导弹和卫星目标间的运动特性差异,给出了预警雷达基于最小矢径这一特征区分弹道导弹和卫星的流程,并分析了弹道导弹射程、雷达测量精度、观测时间、采样间隔等因素对此流程的影响。仿真结果表明:利用最小矢径实现弹道导弹和卫星的区分是可行的,而且此法对雷达测量精度要求不是特别高。

| Abstract: | By analyzing the characteristic of target recognition task and the difference in motion between ballistic missile and satellite in ballistic missile early warning system,the target type classification flow chart is presented based on minimum radius vector.Then the influence of missile scope,radar measurement precision,observation time and sampling interval,to the flow,are analyzed.The simulation results show that distinguishing ballistics missiles from satellites by the minimum radius vector is feasible.And this method does not need very precise radar measurement. |
