利用InSAR技术提取地质灾害信息的对比研究

摘要

目前遥感技术已经成为地质灾害监测得主要手段之一.首先详细阐述了利用卫星遥感影像提取地质灾害信息的方法,并以滑坡为例对国内外研究现状进行了综述.然后通过实例说明了利用InSAR技术提取地质灾害信息的有效性;通过对比研究,给出了雷达影像在监测地质灾害中的优势和不足.最后提出要综合利用多卫星来进行监测,以提高地质灾害信息提取的精度.%Remote sensing technique has been the main method of monitoring geological disasters. The method of using satellite images to obtain the information of geological disasters is introduced firstly, and the study of its application and development in the world are reviewed in brief. Then InSAR techniques as the useful tool for detecting geological disasters have been illustrated by an example. Comparing with satellites, the radar images have many advantages. Finally, the radar and satellites images should be utilized synthetically in monitoring geological disasters.
