【摘要】：針對礦區(qū)地表大量級形變導(dǎo)致的InSAR影像配準(zhǔn)精度低、可監(jiān)測性差、探測量級小、地表沉陷前后完整形變信息難以獲取等問題,研究了相應(yīng)的偏移量追蹤法、FFT過采樣法、濾波技術(shù)與基線精化等數(shù)據(jù)處理方法,并利用短基線集(small baseline subset,SBAS)技術(shù),使距離向配準(zhǔn)精度、最大累積探測量級得到明顯提高,礦區(qū)地表形變可監(jiān)測性有了很大改善。研究結(jié)果表明,該方法不僅獲得了2008—2011年間研究區(qū)開采進(jìn)程中地表大量級沉陷的完整形變時間序列,而且其監(jiān)測結(jié)果與外業(yè)實測數(shù)據(jù)以及采礦進(jìn)程資料具有良好的一致性;通過對礦區(qū)地表形變剖線的統(tǒng)計分析,得到了開采工作面地表形變的時空演變規(guī)律。
[Abstract]:Aiming at the problems of low registration accuracy, poor detectability, low detection order and difficulty in obtaining complete deformation information before and after subsidence caused by a large number of ground deformation in mining area, the corresponding migration tracking method and FFT oversampling method are studied. Filtering technique, baseline refinement and so on, and using the short baseline set small baseline subset SBAStechnology, the range registration accuracy and the maximum cumulative detection order are obviously improved, and the monitoring ability of the surface deformation in the mining area is greatly improved. The results show that this method not only obtains the complete deformation time series of a large number of ground subsidence in the mining process of the study area from 2008 to 2011, but also has good consistency with the field measured data and mining process data. Based on the statistical analysis of surface deformation profile in mining area, the temporal and spatial evolution law of surface deformation in mining face is obtained.
