| Abstract: | To satisfy the requirement of radar signal acquisition and analysis,a high speed radar signal acquisition card based on PCI bus was designed,on which basis a virtual oscilloscope used to analyze and measure radar signal was developed.The driver is WDM type recommended by Microsoft,and was developed in Driver Studio development environment;the application software was developed in Microsoft Visual Studio.NET2003 with C .The oscilloscope realized the functions of acquisition control,waveform displaying and signal measurement and analysis.Furthermore,it achieved expanded functions of frequency analysis and redisplaying of the waveform saved at any time,which can't be accomplished by the traditional oscilloscope.Now the virtual oscilloscope has been used in actual radar experiment. |
