摘要 利用天津地区的2003年10月至2006年2月14幅ENVISAT/ASAR影像进行二轨差分干涉测量实验,选取相干性好、高程模糊度较大的9幅干涉图以叠加方法进行了时间序列分析,获取了地表年沉降速率,得出的地面沉降趋势与实地水准测量结果较为一致,两者较差绝对值小于6 mm,较差的标准偏差为±3.0 mm。 Based on 14 ENVISAT/ASAR images (from Oct. 2003 to Feb. 2007), the interferograms are obtained by two - pass differ- ential InSAR (DInSAR) technology. Nine interferograms with higher coherence and larger height ambiguity are selected to make time serial analyse by interferogram stacking method. The land subsidence results acquired by stacking method show consistent with those inferred from ground leveling at 0.95 confidence level. The difference between DInSAR and leveling is ± 6 mm, and STD is ± 3. 0 mm.
