【摘要】 基于煤矿区地表沉陷的基本特征,论述了合成孔径雷达差分干涉测量(D-InSAR)技术的基本原理,阐述了利用该技术提取煤矿区地表沉陷数据的过程及处理方法;分析应用中存在的失相关等问题,提出解决方法并对获取的矿区地表沉陷变形值做进一步的分析,以期得到地表变形值在不同方向上分量值;最后得出结论:D-InSAR作为一种新的沉陷监测技术,在开采沉陷方面有着常规监测手段无法替代的优势,应用前景广阔.更多还原

【Abstract】 Basing on basic character of earth’s surface subsidence in the mine area,the paper discussed principle of Differential Interferometric Synthetic Aperture Radar,expatiated the technology to distill the earth’s surface subsidence data of mine area and data process method.Analyzing the questions existing in the application such as discorrelation etc,to give solution,and further analyzed the obtained the earth’s surface subsidence value,hoping get the heft of the surface’s distortion value in different direction.At last get the conclusion:D-InSAR as a new technology in subsidence supervising which cannot be replaced advantage in mining subsidence comparing with the common supervising method and having very vast applicable forecast.更多还原
