摘　　要：为了产生雷达天线系统测试时所需的自检信号、速度指令等信号,设计了一种基于基于C8051F206和FT245R的混合信号生成系统.该系统利用FT245R USB接口芯片实现与上位机通信,并依靠C8051F206高程控性和C语言的高灵活性,可靠地响应上位机指令并实时发送被测件所需的自检信号、速度指令等信号源.介绍了混合信号生成系统硬件设计和软件设计的原理.实际应用表明,该系统能准确地生成被测件雷达天线系统所需的自检信号、速度指令信号,并实时地反馈测试结果.In order to generate self-check signal and speed instruction of radar antenna system test signals, design a kind of mixed signal generation system based on C8051 F206 and FT245R.The system uses FT245R USB chip to realize the communication of upper machine, and rely on C8051F206 high SPC and C language to response the instructions of upper machine in a reliable way and send real-time measured parts required for the self-check instruction ,speed instruction, etc.This paper introduces the principle of hardware design and software design of mixed signal systems. Practical application shows that the system can accurately generate radar antenna system self-check signal, speed signal and real-time feedback test results.
