摘　　要：针对经典的旋转电场矢量法仅适用于校准小规模相控阵天线的不足,提出了一种适用于校准大规模相控阵天线的改进旋转电场矢量法。该方法选取单个阵元作参考通道并依次选取其他阵元作测试通道。通过测量这两种通道的合成电场幅度完成相控阵天线的幅度与相位校准。实测结果表明,该方法得到的校准数据具有较高的精度,可用于补偿大规模相控阵天线且能获得优良的远场方向图。The classical rotating element electric-field vector(REV)method is only suitable for calibrating the small size phased array antenna.To solve this problem,an improved REV method for calibrating the large size phased array antenna is proposed.In the method,a single array element in the center of phased array antenna is selected as the reference channel and other single array element is selected as the test channel respectively.By measuring the synthesized electric field amplitude of these two channels,the amplitude and phase calibration of the phased array antenna could be achieved.The actual measurement results show that the calibration data obtained by this method has high accuracy,can be used to compensate for the large size phased array antenna and obtain excellent far-field patterns.
