摘　　要：主要介绍了复合调制信号测量校准系统的设计和实现。复合调制信号是经过调幅,然后再进行调频的信号,主要应用于制导系统中,为了保证测量的准确性,设计了能自动产生调频调幅的复合信号,并能进行测量的自动测量校准系统。本文就该系统作了较为详尽的介绍,包括系统软硬件组成与整体方案设计、软件开发平台的选择、系统的功能和模块设计、测量校准系统的仪器控制方式等。并对设计中的2个关键技术,即信号同步和滤波器的设计进行了详尽的论述。还介绍了系统的试验的结果,试验的结果表明,系统完全符合设计的要求,目前该系统已在实际测量中使用。The article introduced the designing and implementation of composite modulation signal＇s measurement calibration system. Composite modulation signal was through amplitude modulation and then frequency modulation, which was mostly applied in the guidance system. In order to ensure the accuracy of measurement, we designed the automatic producing composite modulation signal of amplitude modulation and frequency modulation, and the automatic measurement calibration system. This paper introduced the system, including the component of system＇s software and hardware, blue print, choice of software development platform, function and the modules designing, and also the way of controlling instrument for measurement calibration system. We also expressed the key technology at large, signal synchronization and designing filter. This article also got the result of experiment and the result showed the system meets the designing requirement. Now the system was applied in the practice measurement.
