摘　　要：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。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 engineering practice.
