【摘要】 合成孔径雷达干涉测量(interferometric synthetic apertture radar,简称InSAR)因具有全天候、连续获取信息和高空间分辨率的特点而被广泛应用于地学、海洋、资源探测及灾害监测等众多领域。在介绍InSAR技术获取地表形变信息基本原理的基础上,重点讨论InSAR技术在矿区地表形变监测中的的几个关键技术问题,包括SAR图像的获取和选择、SAR影像配准算法、水平地形效应的消除、相位解缠和数字高程模型的提取等,并结合国内外应用实例展望了发展前景。更多还原

【Abstract】 Interferometric synthetic apertture radar(InSAR) is widely used in geosciences,marine geodesy,resource exploiting,calamity monitoring for its all weather and 24-hour continuous surveying capability and high spatial resolution.On the basis of a brief explanation to the principle of InSAR,we focus on the key techniques in monitoring the deformation of mining areas,including SAR image acquisition and selection,SAR Image registration algorithm,the elimination of the Effect of Flat Ground,phase unwrapping and the extraction of digital elevation model.Moreover,we predict its developmental tendency with examples of InSAR home and abroad provided.更多还原
