N2 - In order to implement the SCANSAR algorithm based on high-speed digital signal processing system, the Space-borne SAR SPECAN imaging algorithm and the geometrical mosaic algorithm are discussed in detail, and a real-time SAR processor, which is based on DSP boards, is introduced. Both the principle of SPECAN and the mosaic algorithm are carefully analyzed in detail and realized. Furthermore, in order to achieve a high processing efficiency, the parallel structure (SIMD software mode) is adopted in this system, the token rule is brought to improve the local DSP bus accessing speed on a board, and the real-time performance of the DSP system is deeply studied. Finally, the image of SPECAN algorithm is given.
