摘要
介绍了一种相控阵天线有源驻波测试系统。首先对天线有源驻波理论进行分析,然后介绍了天线有源驻波的测试原理及测试系统的硬件组成及软件功能,并对测试系统的测试误差进行了分析。设计完成的测试系统具有测量速度快、灵敏度高、动态范围大、测量误差小、可拓展性强的特点,具有单次测量就可以得到天线多频点多波位匹配特性的能力。
A measuring system for active VSWR of phased array antenna is introduced.Firstly,the theory of antenna active VSWR is analyzed,then the principle of antenna active VSWR test,the hardware composition and software function of the test system are introduced,and the test error of the test system is analyzed.The designed test system has the characteristics of fast measurement speed,high sensitivity,large dynamic range,small measurement error and strong extensibility,and has the ability to obtain the multi-frequency point and multi-wave position matching characteristics of the antenna in a single measurement.
