Abstract:Designing and implementing a Video SAR (Video Synthetic Aperture Radar, SAR) high-speed processing system through a Field Programmable Gate Array (FPGA), which can achieve an imaging processing speed of 5 frames per second. This paper proposes a high-speed processing scheme based on PFA imaging algorithm, which lays a foundation for the real-time performance of video SAR imaging processing. The system realizes radar imaging multi-pulse parallel range processing and high-precision SINC interpolation parallel azimuth processing. The design is verified by the Xilinx Virtex7-XC7VX690T-2FFG1761 development board. The test results show that the system can achieve 2048∗2048 points single-precision complex image imaging processing in 0.18 seconds at a frequency of 200MHz. The real data processing results verify the reliability and effectiveness of the system. © 2019 IEEE.
