Acquisition System For Computer-based Radar Data Of The Pci Bus

In the dissertation, we describe the implementation of large capability radar data acquisition system based on PCI bus of computer. The system is composed of data acquisition card and corresponding software. The data acquisition card includes two acquisition channels , 12-bit digitization at rates up to 20MHz/ch.First, the architecture of the radar data acquisition system is studied. Then, the function and implementation method of each module are introduced in detail. The control module of the radar data acquisition card is implemented by using of the ISP technology of CPLD and the VHDL programming technology. And the double buffer technology is used for large capability data acquisition, because a continuously large memory is difficult to apply in Windows operating system. The application software of the radar data acquisition system is developed by using VC 6.0, and the device driver by using device driver development toolkit-Windriver.
