摘要
幅相特性对于雷达非常重要,直接影响雷达的跟踪性能,嵌入式雷达幅相特性测试仪,采用嵌入式Linux操作系统,以PC/104总线CPU模块为核心,配以幅相特性测试虚拟仪器卡和测试软件构成;该测试仪能完成多种雷达天线馈电线系统、接收系统宽带微波信号幅度差与相位差测试的自动引导,在测试精度、测试方法、操作使用等方面都优于以前的仪器,该测试仪在雷达BIT整机性能监测系统中得到了应用,显著改善了雷达的测试性。
The amplitude phase characteristics is very important to radar tracking performance. The radar amplitude phase characteristics measuring instrument based on embedded Linux operating system is composed of amplitude phase characteristics measuring virtual--instrument card and testing software. The instrument core is CPU module based on PC/104 bus. This instrument can complete the testing and auto guidance of microwave signal＇s amplitude--difference and phase--difference for radar antenna feeder system and receiver system. It also has many excellence superior to former instrument, including measurement precision, measurement method, operation and so on. This instrument was applied in the integrated performance monitoring system of radar＇ s intelligent BIT and the radar＇s testability is improved.
