摘　　要：研究了在被测天线的口径面与平面近场测量面不平行时 ,将近场测量数据到天线口径面的变换转化成对矩阵方程的求解 ,采用奇异值分解法 ,在最小二乘意义下求出天线口径面上的幅相分布 ,对天线进行诊断和校准 ,并通过实验验证了该方法的有效性和实用性。When the aperture plane of antenna under test is not parallel to the plane of near-field scanning, conversion of the antenna under test plane near-field data into aperture-field data is performed by solution of matrix equations, and solving for amplitude-phase distribution of aperture field of the antenna under test by a least-squares solution is obtained via a singular value decomposition algorithm. It is used to diagnose and adjust the antenna under test. It is verified by experiment that the method is effective and practical through.
