随着遥感技术的发展及防灾减灾救灾经验的积累，中国在灾害遥感研究与应用服务上取得了丰硕的成果。总结了我国灾害遥感技术的发展，从数据获取方式和成像方法2方面阐述了合成孔径雷达(SAR)三维成像技术的研究情况，重点介绍了国内外SAR三维成像技术在灾害遥感中的应用现状及潜力。将SAR三维成像技术广泛用于灾害遥感还需要在系统设计、成像分辨力提升、观测场景建模及可视化、灾害系统理论及灾害遥感信息融合等方面进行重点研究。

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.
