摘　　要：为解决地基相控阵雷达对弹道目标探测的最优部署问题,建立弹道中段目标轨道运动和进动模型,提出弹道中段多部地基相控阵雷达的弹道目标探测概率模型,以及平均检测概率、稳定跟踪时间和资源冗余时间3种组合的雷达探测性能评估指标。依据弹道目标RCS及探测距离随观测时间的变化情况,通过仿真实验对多种部署方式下地基雷达对弹道目标探测性能评估指标的分析,得出的结论为弹道导弹防御系统中地基雷达的部署方式提供了有效的参考依据。In order to solve the optimal deployment problem of ground-based phased array radar in detecting ballistic targets,the orbit motion and precession motion models of ballistic targets were built up,and the detection probability model for ballistic targets by using several ground-based phased array radars was proposed.Three evaluation indexes of radars＆#39;detection performance were given： average detection probability,stable tracking time and resource redundancy time .According to the variation of RCS and detection range for ballistic targets in midcourse,detection performance evaluation indexes of several radar deployment schemes were analyzed through experiments .The conclusion in this paper may provide some reference for deploying the ground-based radar in ballistic missile defense （BMD） system for targets＆#39;optimal detection.
