| Abstract: | In this paper, research background of interpretation of SAR imagery is briefly reviewed. Then interpretation technologies are introduced and discussed from speckle noise suppression, edge detection, image segmentation to targets detection and recognition. Based on the analysis and comparison, key factors in interpretation of SAR imagery are concluded as suggestion to future research, such as: using new features and information acquired from SAR imagery and new research theories, fusion of satellite images of different sensors, the utility of artificial intelligence and so on. |
