摘　　要：提出了一种基于坐标变换技术的宽角扫描相控阵天线测量的新方法,用于解决常规平面近场测量方法难以对宽角扫描相控阵天线进行精确测量的问题.在对用于宽角扫描相控阵天线测量的坐标变换技术进行理论分析的基础上,采用计算机模拟对该测试方法进行了数值仿真,制作天线实物进行了试验验证.数值仿真结果和试验结果均表明,该方法用于宽角扫描相控阵天线的测试具有较高的准确性.This paper proposes a novel method to measure the wide-angle scanning phased array antenna based on coordinate transformation, in order to solve the problem of planar near-field antenna measurement in the wide-angle scanning phased array antenna. On the basis of coordinate transformation theory analysis, computer numerical simulation is completed and the physical antenna is fabricated and measured. The results illustrate that the measurement method presented in this paper has a good accuracy to measure the wide-angle scanning phased array antenna.
