摘 要:
InSAR技术能够获取大面积、连续、高精度的地表垂直形变信息，可用来监测地震、火山、滑坡等自然灾害造成的地表形变。文章介绍了InSAR技术在监测陕北黄土地区滑坡中的应用，首先进行野外地质勘察和TM光学遥感影像解译，接着通过EnviSat SAR数据差分干涉处理，获取研究区干涉形变场，提取出滑坡位移量，最后详细分析黄草湾至董家寺沿线一带的滑坡变形范围，并划定出了4个有一定变形的重点监视区。[著者文摘]

Abstract:
Continuous and high-accurate vertical deformation of a large area can be obtained with InSAR. The InSAR is an effective technology for monitoring the earth surface deformation caused by some natural disasters, such as earthquake, volcano eruption, and landslide. This paper introduces the application of InSAR on monitoring landslides in loess area in Shanxi province. Firstly, we carried the wild geological investigation and optical interpretation of TM remote sensing images. Then, with D-InSAR processing of EnviSat SAR data, we obtained the interferometric deformation field and the displacement of the study area. Finally, we detailedly analyzed the deformation ranges along Huangcaowan-Dongjiasi line, and plotted four important monitoring areas where great displacement occured.[著者文摘]
