摘　　要：文中对数字相控阵天线阵面的暗室测试方法进行了研究,阐述了数字相控阵天线阵面的基本工作原理,针对其对测试系统的同步要求,以及不同时刻采样数据的相参要求,提出了专门的测试方法,并搭建了一套测试系统,通过对天线阵面样机的试验,验证了测试方法的正确性和准确度,为数字相控阵雷达天线阵面测试技术的发展提供了技术支持。Test method of the digital phase array radar is studyed in this paper, and working principle of digital phase array radar is expounded. According to the requirement of signal synchronization and coherent, a novel test method is approached. A prototype was tested by the test system established using this method. The results are in good consistence with those in far field tset, which confirms the correction and feasibility of the test method. It provides technical support for the development of test method of digital phase array radar.
