Pci Bus-based High-speed High-precision Data Acquisition

The background of this thesis is scene surveillance radar, which is mainly applied in target imaging, recognizing and tracking at airports. This thesis mainly discusses the front-end of the high-speed signal process in the system. Namely, it involves the radar echo video signal sampling. By using the high-speed, high-resolution and high-performance analog-to-digital converter and the special PCI bus interface chip, we complete the design, test and analysis of the this sampling system. The experiment results prove that it satisfies the design demands.The main content and works of the thesis are present as follows: 1. Design the double channel A/D converter units by using AD6645-80AST.2. Design the PCI bus Interface unit by using AMCC S5920 chip.3. Complete the WDM driver program of the PCI card and the user application interface based on MFC.4. Complete the whole hardware and software test and analysis of this sampling system.
