为了对天线进行高精度的定位或测量，天线相位中心误差是主要的误差源，因此需要对天线相位中心进行精确定位。本文根据天线的相位方向图和幅度方向图的实测数据，利用最小二乘法计算出天线的相位中心偏差。在测量精度小于1 mm的情况下，该方法可以准确、方便地测量出相位中心。
To locate or to measure antenna with high precision, the error of antenna phase center is the main error source, so it is necessary to locate antenna phase center accurately. In this paper, based on the measured data of an antenna phase pattern and amplitude pattern, using the least square method, we can compute the antenna phase center deviation. And with the measurement accuracy less than 1 mm, the proposed method can accurately and conveniently measure the phase center.
