| Abstract: | The integrated SAR system design approach is studied, according to the theory of the processing of SAR images and the high performance of the digital signal processing with FPGA. It is based on the technology of retiming, folding and unfolding, pipelining and parallel processing, having greatly improved its calculation accuracy and speed. The function simulation verification shows that the system can complete the real time processing of space-borne SAR images efficiently. |
