| Abstract: | The CLEAN algorithm, which is often used in the image processing, is incorporated effectively into SAR (synthetic aperture radar) imaging algorithm, and a SAR image side-lobes reduction method based on CLEAN is proposed. By analyzing the process of this method and comparing the imaging results of point target with the oceanic sparse scene imaging results of the RADARSAT-1 raw data, we come to the conclusion that the proposed method can effectively suppress the side-lobes of the targets while preserving the SAR image resolution. |
