Abstract
In order to implement quick-look algorithm based on high-speed digital signal processing system, space-borne SAR quick-look image processing algorithm is discussed in detail, and a real-time SAR processor, based on digital signal processor boards is introduced. According to the hardware architecture of DSP card, the decomposing scheme of finite input response range Doppler (FIR-RD) algorithm is analyzed. In order to solve the problem of storage of the DSP card, the new data-packing scheme is discussed in detail and realized. High quality image of quick-look system is achieved.
