反导任务下一种相控阵雷达搜索参数优化方法

Method of Search Parameters Optimization of Phased Array Radar for Antimissile Mission

搜索参数优化设计是相控阵雷达探测性能提升的重要途径。在相控阵雷达反导任务背景下,针对导弹类目标建立了以最大期望发现距离为目标函数的搜索参数优化模型,在目标匀速运动和加速运动的条件下分别给出了雷达搜索波束最佳驻留时间以及相应目标期望发现距离的优化表达式,仿真证明了算法的有效性。

Optimization of search parameters is an important approach for phased array radar search performance improvement. For antimissile mission, an optimization model of search parameters is built based on analysis of missile features, then the expression of radar＇ s best search beam dwell time and cor- responding expected discovering range are provided under in the condition of both uniform motion and u- niformly accelerated motion. The simulation proves the validity of this method.
