摘　　要：针对开放式天线测试远场的外部干扰问题,介绍了一种快速、简单、有效的方法对天线测试方向图进行误差修正。利用最小二乘法对天线测试方向图中的幅度、相位信息进行等效圆分析处理和误差修正,给出了详细的理论分析,并通过实验验证了该方法的有效性和可行性。该方法的补偿精度能够满足实际工程要求指标,有望在后续的天线测试技术中进行推广和应用。A fast,simple and effective method for error correction of antenna pattern is introduced in this paper for at the external interference in open far field for antenna measurement.The detailed theoretical analysis is provided for equivalent circle analysis processing and error correction of amplitude and phase information in the antenna pattern with least square method,and the effectiveness and feasibility of the method are verified by experiments. The compensation accuracy of this method can achieve the engineering specifications,and it is expected to be wide-ly promoted and used in antenna measurement technology in the future.
