摘　　要：雷达回波采集的目的是为雷达数据处理和目标检测、定位、跟踪做必要的准备。本系统采用带有RAID适配卡的工控机作雷达视频回波采集的主控设备,设计了基于FPGA的雷达信号高速采集卡。利用FPGA内部双口RAM的乒乓切换与缓冲区环行存储技术保证了连续采集。采用数据抽取、坐标查表映射等技术在微机显示器上以PPI(平面位置)方式进行实时显示。试验结果表明本系统能够对每秒50万点的雷达回波信号进行实时高速连续采集、存储和实时显示。The aim of radar signals acquisition is to prepare for radar data processing,target detection,ranging and tracking. The system employs a microcomputer with a RAID card as the acquisition control equipment. A high speed,FPGA-based radar signals acquisition card is designed. The system uses dual-port RAM in FPGA and buffer storage to provide continuous acquisition,and data selection,coordinate inquiry-list mapping technique to imple-ment real-time PPI display on microcomputer monitor. Test result shows that the system can collect,store and real-time display radar signals at a speed of 500 thousands data-sets per second.
