远程相控阵雷达担负目标搜索任务时，在一定检测概率下，特定波位的驻留时间与脉冲重复周期密切相关，如何优化设计脉冲重复周期值以节省时间资源，是一个值得研究的问题。针对远程相控阵雷达单帧搜索工作方式，提出了一种基于最小捕获时间的参数优化设计方法，并以探测临近空间高超声速目标为例，分析了捕获时间与脉冲重复周期之间的关系，给出了最优脉冲重复周期值的赋值区间。仿真结果表明，所提方法能有效节省雷达系统时间资源。

When the long-range phased array radar searching the targets,the residence time of a beam varies with the pulse-repetition period under a given detection probability,so the optimization of the pulse-repetition period is a problem needed to study.Considering the single frame searching mode of radar system, a parameter optimizing method based on the criteria of minimal capturing time for the detection of the near space hypersonic target is proposed.The relationship between the capturing time and the pulse-repetition pe-riod is analyzed.The optimal region of the pulse-repetition period is gives.Finally,the results of extensive simulations demonstrate that the pulse-repetition period can be optimized effectively to reduce the capturing time by use of the proposed approach.
