Recently, the synthetic aperture radar (SAR) has been increasingly in demand due to its advantage of beingable to observe desired points regardless of time and weather. To utilize SAR data, first of all, many preprocessingsuch as satellite orbit correction, radiometric calibration, multi-looking, and geocoding arerequired. For analysis of SAR imagery such as object detection, change detection, and DEM(DigitalElevation Model), additional processings are needed. These pre-processing and additional processes arevery complex and require a lot of time and computational resources. In order to handle the SAR imageseasily, the institutions that use SAR images develop analysis tools and provide users. This paper introducesthe function and characteristics of representative SAR imagery analysis tools. |
