Real-time Acquisition System of Radar Echo Signal Based on PCI8001

In this paper, the design of real-time radar signal acquisition system based on domestic PCI8001 data acquisition card was introduced. By DMA, interrupting collected data was written to the industrial control computer with windows XP system. The technologies of multi-threaded processing, north error correction and pseudo-colored fast algorithm were used in software system. The acquisition of real-time radar video echo signal was realized by the system, display and storage. The system has been used in outside data collection of marine radar successfully.
