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.
