Design Of Radar Signal Generator Base On Pci Bus

Radar simulator takes the important role in seafarer training, assessment of competence, etc. Radar simulator has been demanded higher performances along with rapid development of marine industry. And the explicit standards are clearly defined by STCW 78/95 Convention.Radar signal generator is the kernel part in the radar simulator with true radar display. It real-time generates simulative radar video, trigger, azimuth signal and so on, which display on the true radar screen. Sailor can operate the true radar in simulative sea area environment.After analyzing the radar system, this treatise brings forward base on PCI bus radar signal generator. It is composed of the TMS320VC5402 system and the interface with true radar display and the correlative circuit with PCI2040 chip. It is a comparatively independent radar signal generator system. Communicating with PC based on PCI bus, it can real-time generate radar video signal which display on real radar screen. It adopts the special arithmetic that generates a point by intersecting of two beelines. There isn' t defect such as generating the radar video by table look-at bitmap. The radar image is more verisimilitude, and it is better to simulate sea echo suppression, anti clutter rain, etc.
