| Abstract: | The enhanced Lee filter is used to filter the spot noise that affects the performance of SAR image matching,which is an effective pre-processing method for SAR images.In order to improve the efficiency of pre-processing algorithms,it is optimized and implemented according to the characteristics of FPGA design.The experiments show that the spot noise of SAR image can be removed and the higher rapidity can be achieved. |
