Implementation of high performance signal processing system to generate spaceborne SAR imagery products

To produce different levels of spaceborne SAR imagery product, a real-time/near real-time signal processing system is discussed. Based on analysis of optimization of SAR signal processing algorithm, especially in CS imaging and normal geometric correction for level 1-2 product, the implementation of these algorithms on specific hardware is elaborated. The structure and design of the entire system provide great flexibility and high performance. Finally, some experiments and tests have been carried out to verify the feasibility of the system in high-resolution SAR signal processing.
