First , based on phased array antenna ' s mono - pulse goniometry and separate coordinate technology about phase control , the antenna beam pointing error formula , caused by phase quantization error , is derived from linear array and circular array to planar array and cylindrical array 首先以单脉冲相控阵天线测角原理为基本理论出发点,利用相位控制的坐标分离技术,基于线阵、圆形阵等简单形式的相控阵天线,推导了平面阵、圆柱面阵等相控阵天线由相位量化误差引起的波束指向误差公式。
