| Abstract: | Synthetic Aperture Radar (SAR) has become one of the important tools for mapping shallow sea bottom topography. This technique has significant economic efficiency compared with the traditional techniques. Numerical models have been developed to simulate shallow sea bottom topography SAR images. Inversion of these models makes it possible to assess the water depths from SAR images. This paper reviews these numerical models of SAR technique for mapping shallow sea bottom topography, and examples are illustrated including in the coastal areas of China. Some issues about SAR technique available and the research orientation in the future are also discussed and concluded. |
