随机馈相 meaning in English

random phase feed

However , the optimal results being a statistical average , the antenna pattern of random phasing is unsteady with the scanning angle and scanning period , so it is not easy to form the actually needed codes for control of the antenna scanning
应用遗传算法对随机馈相方案进行优化，能有效抑制寄生副瓣的出现，形成扫描空域确定的波控代码，实现相控阵波束无惯性的精确指向。
