摘　　要：相控阵天线暗室测量在相控阵天线研制中起着重要作用。在暗室测量中,为了解决相控阵天线测量内容多、效率低、精度低、系统普适性差、成本高的问题,本文设计出一款通用波控分机,通过硬件设计,预留多种通信接口,固定接口协议,适用多类相控阵天线;通过软件编程,精确测量脉冲、波束切换时间,匹配暗室测量系统,应用到平面近场暗室、紧缩场暗室测量中,并给出测试流程及时序图。实验结果分析表明,多波位与单波位测量方向图扫描精度基本一致,测试效率显著提升,降低测量成本。通用波控分机的应用,实现不同类型多波位相控阵天线在微波暗室中快速、准确的测量。Microwave laboratory measurement of phased array antenna plays an important role in the development of phased array antenna.In the microwave laboratory measurement,in order to solve the problems of phased array antenna measurement content,low efficiency,low precision,poor system universality and high cost,this paper designed a general wave control extension,through hardware design,reserve a variety of communication interfaces,fixed interface protocols,suitable for multi-class phased array antennas.Through software programming,the pulse and beam switching time are accurately measured,and the microwave laboratory measuring system is matched to the plane near-field darkroom and tight field darkroom.The test process and sequence diagram are given.The experimental results show that the scanning accuracy of multi-wave position and single-wave position measurement pattern is basically the same,the test efficiency is significantly improved,and the measurement cost is reduced.Rapid and accurate measurement of different types of multi-wave phased array antennas in the microwave laboratory is realized by the application of general wave controller.In the microwave laboratory measurement,in order to solve the problems of phased array antenna measurement content,low efficiency,low precision,poor system universality and high cost,this paper designed a general wave control extension,through hardware design,reserve a variety of communication interfaces,fixed interface protocols,suitable for multi-class phased array antennas.Through software programming,the pulse and beam switching time are accurately measured,and the microwave laboratory measuring system is matched to the plane near-field darkroom and tight field darkroom.The test process and sequence diagram are given.The experimental results show that the scanning accuracy of multi-wave position and single-wave position measurement pattern is basically the same,the test efficiency is significantly improved,and the measurement cost is reduced.With the application of general wave
