Abstract:With the development of remote sensing technology and the accumulation of experience in disaster prevention and relief, China has made fruitful results in disaster remote sensing research and application services. The stages of development of China’s disaster remote sensing technology are introduced. 3D Synthetic Aperture Radar(SAR) imaging technology is discussed from two aspects: data acquisition mode and 3D imaging method. The application potential of SAR 3D imaging in disaster remote sensing is highlighted. It is pointed out that the system design, image resolution enhancement, observation scene modeling and visualization, disaster system theory and disaster remote sensing information fusion will be the focuses of future research.
