基于FPGA的万兆以太网在雷达数字前端设计中的实现OA

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,prepro-cessing,and high-speed data transmission,resulting in a radar processing front-end with a simple hardware structure,high signal pro-cessing capability,and fast data transmission speed.To meet the data transmission capacity requirements,in the software implementa-tion,the high-speed data read-write timing is meticulously designed according to radar waveform characteristics.This design has been successfully applied in real-time processing for surveillance radar projects,achieving excellent results.
