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