摘　　要：天线测量是天线研究过程中一项重要而又繁杂的工作,在对高性能雷达天线的研制过程中,离不开一套高精度的天线测试系统。影响天线测试系统精度的因素很多,从测量环境微波暗室、天线发射控制系统、天线接收控制系统等几方面设计了一种多通道天线测试系统,用来测量和分析天线辐射特性的各种电磁参数。设计完成的测试系统具有测量灵敏度高、动态范围大、测量误差小、抗干扰能力强和天线原始数据采集速度快的特点,具有一次性扫描测量就可获得多频点、多通道天线数据的能力。Antenna measurement is an important and complex work in antenna research process.High-performance radar antenna in the development process can not do without a high-precision antenna test system.The performance of antenna test system 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 is completed with high sensitivity,dynamic range,small measurement error,strong anti-interference and antenna original data acquisition fast.It can be measured with one time scanning to obtain multi-frequency and multi-channel antenna test data.
