This paper presents the design of a high-speed real-time signal processing radar digital front-end based on Xilinx FPGA.The FPGA in this radar front-end fully utilizes its abundant resources, including logic, RAM,DSP, and high-speed interfaces, to implement functional modules such as 10-Gigabit Ethernet, Microblaze, and high-speed cache. This enables the FPGA to perform control, preprocessing, and high-speed data transmission, resulting in a radar processing front-end with a simple hardware structure, high signal processing capability, and fast data transmission speed. In software implementation, the high-speed data read-write timing is meticulously designed according to radar waveform characteristics to meet the data transmission capacity requirements. It has been successfully applied in real-time processing for surveillance radar projects, achieving excellent results
