Active phased array radar antenna subarray division method

Abstract

本发明公开了一种有源相控阵雷达天线子阵划分方法。所述有源相控阵雷达天线子阵划分方法包括如下步骤:步骤1:获取阵元分布形式、阵元间距、阵元编号并计算坐标向量;步骤2:得到加权向量;步骤3:通过遗传算法对加权向量进行计算,得到初始化聚类中心;步骤4:对初始化聚类中心进行聚类划分,从而得到有源相控阵雷达天线子阵划分形式,并对得到的有源相控阵雷达天线子阵划分形式计算适应度评价函数;步骤5:预设阈值,并判断适应度评价函数是否超过所述阈值;若否,则结束。本申请的有源相控阵雷达天线子阵划分方法融合了遗传算法和模糊C—均值聚类算法,充分发掘两种算法的优点,提出了一种遗传聚类算法。
The invention discloses an active phased array radar antenna subarray division method. The method includes the steps of firstly, acquiring an array element distribution form, an array element distance and an array element number, and calculating a coordinate vector; secondly, acquiring a weighted vector; thirdly, calculating the weighted vector through a genetic algorithm to obtain an initialization clustering center; fourthly, performing clustering division on the initialization clustering center to obtain an active phased array radar antenna subarray division form, and calculating the fitness evaluation function of the active phased array radar antenna subarray division form; fifthly, presetting a threshold, and judging whether the fitness evaluation function exceeds the threshold or not; if not, terminating. The active phased array radar antenna subarray division method has the advantages that the method fuses the genetic algorithm and a fuzzy C-means clustering algorithm, the advantages of the two algorithms brought into full play, and a genetic clustering algorithm is provided.
