摘　　要：针对传统雷达数据采集卡适用雷达类型单一、不能采集雷达监视区域全景数据的弱点,采用可更换接口子卡与可重复编程控制逻辑技术,设计了能够满足多种型号非相参警戒雷达使用的通用雷达数据采集卡,该采集卡能够提供PPI全景图像、A/R视频回波和精采回波等三路数据,能够和多种型号非相参监视雷达连接。使用该方法设计的采集卡已经在多种实用化的雷达目标识别系统中使用。In view of the weakness of the traditional radar data acquisition card which was designed for the special radar system and could not sample PPI image data, a common radar data acquisition card which is fit for many non-coherent surveillance radar systems is designed by adopting replaceable interface sub-card and reprogrammable control logic technique. It provides three channels' data: PPI image data, A/R video data and precise data, and is compatible with many models of non-coherent surveillance radar system. The card designed according to the proposed method is well used in several actual radar target recognition systems.
