相控阵天线远场测试场测量方法

摘要

Appropriate testing method should be selected to test the characteristics of phased array antennas. In order to study the far⁃field testing of phased array antennas,a far⁃field testing field measurement is adopted. The measuring methods of characteristics of EIRP,G/T and antenna pattern are introduced and researched. The beam correction and electric level compen⁃sation are explained. The method can accurately measure the far⁃field performance of phased array antennas and be used in engi⁃neering practice.%　　对相控阵天线的特性需要选择合适的测试方法进行测试，为了研究相控阵天线的远场测试，采用远场的测试场测量，对相控阵天线的EIRP、G/T值以及方向图等指标特性的测量方法进行了介绍和研究，并进行了波束修正与电平补偿的说明，此测试方法可准确测量相控阵天线的远场性能并应用于工程实践。
