中文摘要：
研制了一种适用于雷达中频／视频信号采集的通用雷达数据采集系统。系统以计算机作为采集主控设备，雷达数据的采集由自行研制的雷达采集接口卡与通用雷达数据采集卡来完成，接口卡和采集卡被封装于一个小型的屏蔽盒内，非常便于携带。采集卡与计算机接口采用USB2．0接口，以FPGA为采集的核心控制芯片。采用数据抽取、坐标查表映射和DirectDraw等技术在计算机显示器上以P显和A显方式进行实时显示。显示过程中可对任意区碱设置采集方位、仰角和距离波门，对采集的数据进行实时存储。外场采集实验数据表明，该系统能够满足目前多种型号雷达的采集任务。
英文摘要：
A general radar data acquisition system is developed to acquire radar intermediate frequency or video echo signal. The system uses a microcomputer as an acquisition control equipment, and uses a radar interface card and a general radar data acquisition card to acquire radar data. The interface card and the acquisition card are packaged into a small shielding box. The acquisition card uses USB2.0 as the interface with microcomputer, uses FPGA as kernel chip to control the data acquisition, and uses data decimation, coordinate inquiry list mapping and DirectDraw technique to implement real time PPI display and a scope; display on microcomputer monitor. User can set azimuth and distance gate of any area, and store acquired data at real time. Experimental results of data acquisition show that the system can satisfy the data acquisition task needs of many kinds of the radar.
