Design and Application of a Great Capacity & High-speed Digital Signal Source Based on PCI Bus of Personal Computer
【摘要】 提出了一种基于微机PCI总线的海量高速数字信号源的设计方法,具有成本低、兼容性强、可扩展、通用性好等优点,并成功地将其应用到了合成孔径雷达实时成像处理系统的研制中。
【Abstract】 This paper presents the design of a great capacity, high-speed digital signal source based on PCI bus of personal computer. It has good compatibility and can be easily operated because of the friendly graphical user interface based on Win95/98. As a result of the flexible structure, it is easy to be developed economically. It is successfully applied in the integration of the SAR real-time imaging system.
