摘要
采用PCI-9812数据采集卡和XC2S200 FPGA芯片共同完成测速雷达系统的信号处理,即高速A/D转换模块和频谱的分析,并利用VB语言实现速度时间曲线的拟合问题和终端界面的显示,完成友好的人机交互功能.
In the system, by adopting PCI-9812 simultaneous-sampling analog input card and XC2S200 FPGA chip, the system＇s digital signal process section was completed, such as the A/D transformation module and the frequency spectru＇s analysis. And the question of curve fitting and the interface＇s displaying,the function of man-machine alternating were completed by writing VB software language.
