Multi-DSPs SAR real-time signal processing system based on cPCI bus

SAR real-time signal processing plays a significant role in SAR system, and has been taken as an important means to obtain real-time and effective information in military application. This paper analyzes the basic system requirements in view of the SAR signal processing feature, and a universal design method of system architecture and software realization are presented. Finally, the actual result obtained from a Ku-band radar system is presented to prove that the system design method is feasible.
