Shun Xin Li, Yu Fan Mo · Advanced materials research · 2012
Based on the high-speed, real-time and high precision of radar signal processing, FFT arithmetic is utilized in the radar signal processing and FFT processor is designed and implemented. The proposed processor adopts radix-2 FFT algorithm. FFT computing based on FPGA has the advantages of high speed, less resource occupancy, easy algorithm and convenient system debugging and implementation. It is composed employing VHDL as hardware description language, FPGA as the logic controller, Quartus II as designing and synthesis simulation tool. The simulation results indicated FFT processor approached the request of the radar signal processing and it is suitable for the application of high-speed signal processing
