摘要:新一代高分辨率、短重访周期 SAR 卫星的发射运行,不仅能满足时间序列 InSAR 技
术在大范围地表沉降监测方面的数据需求,还可以监测到大型人工线状地物的形变,使得
对短周期、微小形变的监测和预警成为可能。本文以上海市在运营的磁悬浮列车专线为研
究对象,利用时间序列分析方法对 2011 年 9 月至 2012 年 10 月期间的 15 景 TerraSAR-X 数
据进行了处理和分析,实验结果表明高分辨率 SAR 数据可以用于公共交通设施微小形变的
监测,在公共安全领域具有广阔的应用前景。

Abstract: With the appearance of high resolution, short re-visit cycle radar satellite data, it can not
only be used in monitoring land subsidence in large area, but can be used in obtaining the
deformation of large buildings and work and made the short-term small
deformation monitoring possible. In this paper, time-series analysis of InSAR data is carried out to
detect the deformation of Shanghai maglev track. The dataset of 15 TerraSAR-X images were
acquired from September, 2011 to October, 2012. Experimental result shows that high resolution
SAR data has a good prosp
