摘　　要：基于干涉仪测向的应用背景,本文研究了一种基于紧缩场测试系统利用射频矩阵开关校正天线单元相位一致性的快速测试方法。相对于将天线阵列单元的相位中心放置于测试转台的中心进行测试的传统方法,该方法不仅能够减少烦琐的操作步骤,而且大大压缩了测试所需要的时间。经过验证对比,该测试方法简单可行,具有可操作性,对工程实践具有一定的借鉴意义。Based on the application background of interferometer direction finding,this article studies a fast test method based on the compact antenna test range system and using radio frequency matrix switch to correct the phase consistency of the antenna unit.Compared with the traditional method of placing the phase center of the antenna array unit at the center of the test turntable for testing,this method not only reduces the tedious operation steps,but also greatly shortens the time required for testing.After verification and comparison,this test method is simple,feasible,operable,and has certain reference significance for engineering practice.
