Abstract
In this paper a new real-time flood monitoring system using SAR is described. Flooding has been a puzzling problem to the Chinese government for a long time. During the last decade, China promoted a research program of flood monitoring and management using remote sensing techniques and established a quasi-real-time and real-time disaster monitoring system. The system has two functions: flood monitoring by SAR and an image transmitting system, and loss estimation of flooded area using an image processing GIS system. This system was used successfully in the 1991 flood in China and played an important role in reducing flood losses. To establish this system several key technical problems were solved, including the SAR system, SAR image processing, SAR image compression, and image long distance communication and information system.
