InSAR技术及其在地质灾害中的应用

InSAR是在太空对地球进行3维成像技术，它标志着空间遥感从2维信息获取进入到3维信息获取的新阶段，也为大地测量带来了一场革命。该技术为地质灾害的研究提供一个全新的工具。运用InSAR和D～In—SAR技术进行地面微位移监测，是近年来发展起来并得到日益重视的新方法。本文例举了InSAR技术在地震、火山喷发和滑坡等地质灾害应用的实例。表明它在形变监测研究中有广阔的应用前景，具有不可替代的优势。

Introduction to InSAR and Its Applications in Geohazards

InSAR is a 3 - D imaging technique from the space to the earth. It indicates that remote sensing has stepped into a new stage from acquiring 2 - D to 3 - D information, and also brings a revolution in geodesy. InSAR is a full new tool in the geohazards re- search. The micro - displacement monitoring using InSAR and D - InSAR technique is a new method and paid highly attention. The paper gives some examples of InSAR application on geohazards such as earthquake, volcano eruption and landslides etc. it shows that InSAR has a great potential and advantage in deformation monitoring research.
