摘　　要：在宽带数字波束形成处理中,一个关键问题是对阵列天线接收到的信号进行包络延时补偿。解决该问题的基本方法是通过分数延时滤波器对输入信号进行延时。本文主要讨论Farrow结构的分数延时滤波器设计优化方法,以便于工程应用。In wide band digital beam forming procession,a key problem is compensation for envelop delay of signals received from antenna array.The basic method to solve this problem is to delay the received signal by fractional delay filter.In this paper,some design optimization methods about Farrow structure fractional delay filter were discussed for engineering applications.
