| Radar display and control terminal is one of the important parts for a radar system. It must control radar accurately, process data from radar effectively and display targets to a radar manipulator with visual, effective and accurate mode. Presently, most traditional radars'control parameters are analog and their display terminals are professional raster display monitors. Detecting targets and acquiring coordinates both depend on radar manipulators in such radars. It baffles data's effective process with its complicated structure, high cost and slow speed. With the rapid development of computer technology, image processing technology and software technology, it has become a new trend to take general purpose computers as radar display and control terminals. Computers can process digital data flexibly, and image processing technology and computer software with strong function can make design of Radar display and control terminal more expediently. Meanwhile, designing radar display and control terminal with software strengthen radar system's compatibility and extensible which provide a new way for radar terminal's development. Taken general purpose computers as radar terminals, there are amount of data need to be transferred between radar and computers, a driver for corresponding communication device is necessary. Aiming at transferring big amount of data with high speed, PCI bus is preferred and programming drivers based on PCI bus become the hinge of communication between radar and computer. This project based on the design of a surveillant radar, is to program a WDM driver for a PCI communication card based on Windows2000 system and its display and control terminal application by Visual C++6.0. |
