High-performance system design of SAR real-time signal processing

Synthetic aperture radar is a high resolution imaging radar, SAR signal processing is an important branch of signal processing, while the performance of SAR signal processing system greatly influences the resolution of SAR image. In this paper, a high-performance signal processing system which has strong computation ability, high-width connectivity and flexible expandability is presented, meanwhile, the program design of FPGA is introduced, further more, the RD algorithm implementation result with the system proposed in this paper is provided as an illustration.
