D-InSAR技术在矿区开采沉陷监测中的应用
APPLICATION OF D-InSAR IN MINING SUBSIDENCE
摘要
Abstract
As a new space geodetic technique, differential synthetic aperture radar interferometry (D-In-SAR) have more advantages than traditional geodetic technique such as all-weather, 24-hour continues surveying and ability to penetrate into substances on the earth. This article introduces the deformation monitoring of YAO QIAO with D-InSAR technology at the basic of explaining the principle of D-InSAR. The cause of few obvious interferometric fringes was analyzed. The precision of the observing data was then assessed compared with the ground-based leveling data, and the initial accuracy assessment is done.关键词
