【摘要】 本文论述了利用星载干涉SAR进行地面沉陷调查研究的基本理论、技术方法及其实施。系统分析研究了利用多源、多时相的干涉SAR数据进行矿区地面沉陷监测中应解决的一些关键技术问题,包括针对有些SAR卫星轨道数据不精确的情况,采用空间基线精估计和几何配准的方法,在煤矿生产区布设水准点和角反射器,通过高精度水准测量和GPS测量,结合星载差分干涉进行地面沉陷的多种技术协同监测以及和地下采矿生产状况进行对比分析等。在河北峰峰煤矿区的试验研究成果表明,星载雷达差分干涉测量和GPS测量、水准测量三种不同的技术方法,在监测矿区地面沉陷的位置、范围和精度方面是基本一致的,并且三者能够起到相互验证的作用；在星载雷达差分相干性较差的一些地区,L波段的测量结果要优于C波段的测量结果;星载雷达干涉测量所监测到的地面沉陷状况(位置和沉陷量)与地下采矿活动进展的互动协同性相当一致,相符率约为90%左右。更多还原

【Abstract】 In this thesis, the basic theories, techniques and their practice using spaceborne InSAR for ground subsidence investigation have been described. The key technology and practical issues by use of Multi-source and multi-temporal InSAR image data for surface subsidence monitoring in a coal mining area have been systematically probed, which include the new methods of space baseline precision estimation, geometry registration of SAR images in the case of no exact satellite orbit data, the integration of high-precision levelling, GPS surveying and D-InSAR measuring, the comparison and analysis between the coal mining activity material and the integrative measuring results of ground subsidence in the mining area. The results of experiments and research in Fengfeng Coal Mines, Hebei province show that the resultants of D-InSAR measuring, precision levelling surveying and GPS observation are coincident in the location, scale and accuracies of mining area subsidence; In general, the measurements using L-band D-InSAR is superior to C-band while SAR interferogram quality was poor in some districts; The locations and degrees of ground subsidence between Spaceborne SAR monitoring and the practical resultants derived from underground mining activities are quite coincidence, keeping with about 90%.更多还原
