Abstract: Phased antenna has many working modes. Aimed at reducing heavy manual work in test of phased antenna, adesign of automatic antenna test system is presented. The system realizes the automatic, unattended test for phased antenna.Compared with manual test, the system greatly improves the correctness and efficiency of the antenna test, and it also realizes theautomatic formatted storage. It is proved to run stably, have high reliability and meet the demand for actual applications.
