| 摘 要： | 新代高分辨军、短重访周期SAR卫星的发射运行，使得InSAR技术不仅能满足大范围地表沉降监测的数据需求，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20112~F9月～2012年10月期间的15景TenaSAR-X数据进行了处理和分析，实验结果表明高分辨军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: | The recently available high-resolution, short revisit-cycle, radar satellite data can not only be used to monitor land subsidence over large areas, but also to provide information regarding the deformation of large buildings and the transportation network; it has also made short-term small-scale deformation monitoring possible. In this paper, time-series analysis of InSAR data is carded out to detect deformation of the Shanghai Maglev track. The dataset of 15 TerraSAR-X images was acquired between September 2011 and October 2012. Experimental results showthat high-resolution SAP, data may be suitable for operational monitonng of deformation affecting public infrastructu re. |
