摘　　要：针对数据量大、传输速度快的无人机机载毫米波雷达数据实时存储需求,以FPGA和微型电脑为核心设计了一款基于FPGA的毫米波雷达数据实时存储系统。该系统通过接收10路LVDS雷达数据和1路串口GPS数据,经过FPGA处理和混合组帧后,将数据打包通过1路千兆网上传给微型电脑,微型电脑通过LabVIEW上位机程序将接收到的数据存储在移动固态硬盘内。实验结果表明,当数据传输速度为30 MB/s时,可准确无误地将数据存储在硬盘内。相比于其他实时存储系统,该系统具有存储速度快、适用范围广和操作简单等特点。In order to meet the real-time data storage requirements of UAV airborne millimeter wave radar with large data volume and fast transmission speed,a real-time data storage system of millimeter wave radar based on FPGA is designed with FPGA and microcomputer as the core.The system receives 10 channels of LVDS radar data and 1 channel of serial port GPS data.After FPGA processing and mixed framing,the data is packaged and transmitted to the microcomputer through 1 channel of gigabit network.The microcomputer stores the received data in the mobile SSD through the LabVIEW upper computer program.The final design of the system has been verified by experiments.When the data transmission speed is 30 MB/s,the data can be accurately stored in the hard disk.Compared with other real-time storage systems,this system has the characteristics of fast storage speed,wide application range and simple operation.
