| Abstract: | Antenna measurement is an important and complex work in antenna research process. High-performance radarantenna in the development process can not do without a high-precision antenna test system. The performance of antenna testsystem is influenced by many factors.A multi-channel antenna test system was analysed and designde from the three factors,including microwave anechoic chamber from the measurement environment,antenna emission and receiving control system.This system is used to measure and analyze all kinds of electromagnetic radiation characteristics of antenna. Test system iscompleted with high sensitivity,dynamic range, small measurement error,strong anti-interference and antenna original dataacquisition fast. It can be measured with one time scanning to obtain multi-frequency and multi-channel antenna test data. |
