摘　　要：采用相位判定方法剔除对测向结果影响最大的天线,自动判别并剔除误差最大天线相位后,重新优化组阵再进行相关干涉仪测向,有效提高了测向精度。介绍了该方法具体实现流程,通过仿真和实际采集测向数据的分析,验证了该方法的有效性。This paper uses the phase decision method to eliminate the antenna which has the greatest impact on the DF accuracy,after automatically distinguish and eliminate the antenna phase with the largest error,continue to regroup,and then do direction finding with correlation interferometer,the direction finding accuracy is effectively improved.This paper introduces the specific implementation process of this method,and through the analysis of the actual collected phase data,the effectiveness of the method is verified.

关 键 词：相关干涉仪测向 查表法 最小二乘法
