摘　　要：在相控阵天线中，初始相位校准的准确性直接影响相控阵波束指向的准确度。通过利用分组旋转矢量法，对不同组合方式的单元通道同时进行矢量旋转，能更好检测到被测信号的变化，并在远场对有源相控阵天线阵面进行相位校准。利用此方法对Ka相控阵进行初始相位校准，有良好的结果。In the phase array antenna, the accuracy of the initial phase calibration directly affects the accuracy of the phased array beam pointing. In this paper, by using the group rotation vector method, vector rotation is performed simultaneously on different combinations of unit channels, which can better the change of measured signal and be calibrated for an active phased array antenna surface in the for field. The Ka is corrected by this method and good results are obtained.
