摘　　要：通过对无源相控阵天线信号形成原理的分析,对已有测试方法进行了详细分析,结合工程实践中对于移相器原位测试的需求,文中提出了一种基于相位扫描的无源相控阵天线的移相器原位测试方法。该方法充分考虑了实际使用过程中对天线移相器检测的要求,做到了免拆除卸下的原位检测,对于现场测试维护提供了理论指导。在分析和仿真测试过程中,充分考虑了工程实践中噪声的影响,并给出了仿真结果。该测试方法的系统仿真结果表明了该方法的理论可行性和工程可实现性。The principle of passive phase array antenna signal generation and the test methods existing are analyzed, and a test method that can test the phase shifter of antenna based on phase scan is proposed. This means considerable emphasis on the requirement of antenna phase shifter in real situation, and provide inspections without dismantling as well as theoretical guide to the on site testing. During the analyzing and simulating work, we concern the influence of the noise that can be encountered during the engineering work, and give the simulate result. The system simulate result shows that the theory feasibility and engineer realizably.
