【摘要】 介绍了差分合成孔径雷达(D-InSAR)技术的基本原理,并以徐州某老采空区为例,对其雷达影像数据进行二轨差分干涉处理,获取其地表形变场。研究表明,D-InSAR技术可以应用于监测大面积的老采空区残余变形。更多还原

【Abstract】 The basal principles of Differential Interferometric Synthetic Aperture Radar(D-InSAR) were described briefly in this paper.Taking an old goaf in Xuzhou as an example,the deformation field of the surface was obtained by processing radar image data with two-track differential interferometric.Studies have shown that the D-InSAR technique can be applied to monitor a large area of the old goaf residual deformation.更多还原
