Design and simulation of one dimensional frequency-domain algorithm based on FPGA

Echo simulation is an important way of SAR (synthetic aperture radar) algorithms research and load testing. While, with the complicated algorithm and large computing, it´s difficult to complete. To realize spaceborne SAR real-time echo simulation, this paper designs a program based on one dimensional frequency-domain algorithm, which operates on FPGA. And the FPGA program design tool is System Generator for DSP.
