摘要：The object of this paper is taking full advantage of ENVISAT ASAR image in differentiating land and water area based on the research of ASAR image character, to work out a efficient method to monitor flood submergence area quickly using ASAR, and to develop a radar processing module focusing on ASAR image. So it can provide a advance practical remote sensing dynamic monitoring method in Flood Control and Hazard Mitigation and disaster evaluation.Base on the remote sensing flood monitoring practice, this paper analyzed the flow of monitoring flood submergence area quickly using ASAR, and developed a special radar processing module in Erdas Imagine software environment. Using this module, and selecting East Dongting Lake as test area, the validity and precision of the module are validated through field investigation and remote sensing monitoring of water area changes in the test area in 2006 and 2007 flood season. Furthermore the water area change of East Dongting Lake in 2006 and 2007 is analyzed
