差分SAR干涉测量已被应用于研究城市地区的位移场。一组 6 张 ERS1/2 SAR 图像已用于检测、绘制和量化佛罗伦萨附近普拉托市（意大利）发生的沉降。在 1993 年至 2000 年期间，该市发现了四个受强烈沉降影响的区域。对相隔两年拍摄的图像处理的三张干涉图的分析表明，变形率是恒定的，最大值约为8.3 cm.yr/sup -1/。
The differential SAR interferometry has been applied to study the displacement field in an urban area. A set of 6 ERS1/2 SAR images has been used to detect, map and quantify the subsidence occurring in the city of Prato near Florence (Italy). Four areas affected by strong subsidence during the period 1993-2000 have been spotted within the city. The analysis of three interferograms processed from images taken two years apart shows that the deformation rate is constant, with a maximum value of about 8.3 cm.yr/sup -1/.
