| 摘 要： | 本文筒要了介绍合成孔径雷达差分干涉测量(D-InSAR)技术的基本原理,并以大屯地区失水沉降为例,对其雷达影像数据进行二轨差分干涉处理,获得地面沉降情况,并由地面检核点验证其结果是可靠的;最后,结合地面抽水情况,分析了沉降与抽水量、地下水位之间的关系:地表下沉的速度与抽水量成正比,与地下水位的升幅成反比.

| Abstract: | The basal principles of Differential Interferometric Synthetic Aperture Radar(D-InSAR) were described briefly in this paper.Taking DATUN as example,the ERS2 images were disposed by the two-pass differential interferometric process method,and the subsidence of this area was obtained.After comparing with the surface observation data,it proved that the results obtained by D-InSAR are very reliable.Finally,the relation between the deformations and the level of groundwater were analyzed,the speed of the subsiden... |
