Design and Implementation of FFT Module Based on Virtex Series FPGA

Abstract:

In order to achieve real-time data output in synthetic aperture radar (SAR) imaging system, high-speed FFT transformation is needed. In this article, we proposed the program that uses the new generation of high-speed, large-capacity Virtex series FPGA to implement radix-4 FFT algorithm and simulated it with the Modelsim software, and then through the comparative analysis of simulation results by MATLAB. After analyzing the results compared with MATLAB simulation, it shows that FFT module has stable performance, fast operation and fully meets the radar data real-time processing requirements.
