摘　　要：文章根据平面近场测量耦合公式,首先由近场数据推导了以切向磁流表征的口径场幅相公式,然后通过实验测试的方式,利用算法反演的口径场进行阵列天线单元幅相的补偿,结果与预期情况符合的很好,证明了此种算法的正确性和有效性。Based on the coupling formula of planar near-field measurement,the formulas of aperture amplitude and phase which is represented by tangential magnetic current is derived from the near filed data. Then by the method of experiment measurement,the amplitude and phase of the array antenna are compensated by the aperture filed obtained from the algorithm. The results are in good accordance with the expected situation,which proves the correctness and validity of the algorithm.
