摘　　要：该文研究了一种基于等效磁流源方法和矩量法的相控阵天线近场到任意近/远场变换方法。根据相控阵天线的平面近场测量数据求解了在假定口径面上的等效磁流源分布,从而进行了近场口面诊断和远场方向图计算。计算结果与远场测量环境下的测试结果吻合良好,验证了该文方法的准确性和有效性。In this paper,the near-field to near/far field transformation for phased array antenna is studied based on the equivalent magnetic current approach.The equivalent magnetic currents on an assumed aperture are obtained from the planer near-field test data via the proposed approach,and then the near-field diagnostic and far-field pattern.It shows that the transformation results agree well with the test results in far-field environment,which demonstrates the accuracy and efficiency of the proposed method in this paper.
