| 摘 要： | 合成孔径雷达差分干涉测量技术是新近发展起来的用于监测大范围地表形变的新技术,具有精度高、监测范围广等特点。文中深入分析DInSAR技术的基本原理,通过实验成功获取西安市中心城区相隔9个月的地面沉降结果,与常规方法获取的沉降图对比,发现二者具有高度的一致性,从而证明利用DInSAR技术监测城市地面沉降具有良好的应用前景。

| Abstract: | Differential Synthetic Aperture Radar interferometry(DInSAR) is a newly developed technique for monitoring large-scale ground deformation with some prominent advantages such as high accuracy and pantoscopic view.This paper firstly gives an introduction to the principle of DInSAR.Then,the ground subsidence over nine months in center area of Xi an has successfully detected using DInSAR technique.Compared with the ground-based measurements,the results are viable and reliable.It also proved the DInSAR technique... |
