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.
