基于D-InSAR技术的矿区地表形变监测研究
|
摘要
本文利用时序Envisat单视复数据(SLC),分别采用"2轨法"和"3轨法"雷达差分干涉测量,对河北邯郸峰峰煤矿地区地表沉降检测试验,检测矿区内地表沉降发生的位置及范围,结合实验分析了差分干涉测量技术在地表形变监测中存在的问题及其应用前景。
Synthetic Aperture Radar interferometry(InSAR) is a rapidly developing earth observation technique.Comparie with leveling and GPS,InSAR had advantages in large area,high resolution,all-weather and low cost,which enabled it to be a potential tool of deformation monitoring.In this paper,two-pass and three-pass methods to obtain the deformation interferogram of Fengfeng-Handan mine in Hebei province of China from Envisat Single Look Complex data.Further more,some limits and merits of DInSAR in deformation monitoring are discussed according to the result of interferometry.
