城市沉降和山体滑坡是对人民和基础设施安全的最大危害，需要特别注意减少其相关风险。在这一框架内，地基合成孔径雷达干涉测量法是精确监测位移的一种成本效益高的解决办法。这项工作提出了GB-InSAR技术的应用，特别是与RiskSAR传感器及其处理链开发的遥感实验室（RSLab）的卡塔卢尼亚大学（UPC），监测两种不同类型的地面位移。一个例子的城市沉降监测的村庄萨伦特，西班牙东北部，和一个例子的滑坡监测在El Forn德卡尼略，位于北比利牛斯山脉，提出。在这个框架中，每个案例的关键处理的特殊性进行了深入的分析和讨论。两种情况下的线性位移图和时间序列的显示和现场数据进行比较。对于这项研究，在X波段与零基线配置获得的全极化数据在这两种情况下。得到的位移结果表明GB-SAR传感器的地面位移现象的精确监测的能力。
Urban subsidence and landslides are among the greatest hazards for people and infrastructure safety and they require an especial attention to reduce their associated risks. In this framework, ground-based synthetic aperture radar (SAR) interferometry (GB-InSAR) represents a cost-effective solution for the precise monitoring of displacements. This work presents the application of GB-InSAR techniques, particularly with the RiskSAR sensor and its processing chain developed by the Remote Sensing Laboratory (RSLab) of the Universitat Politecnica de Catalunya (UPC), for the monitoring of two different types of ground displacement. An example of urban subsidence monitoring over the village of Sallent, northeastern of Spain, and an example of landslide monitoring in El Forn de Canillo, located in the Andorran Pyrenees, are presented. In this framework, the key processing particularities for each case are deeply analyzed and discussed. The linear displacement maps and time series for both scenarios are showed and compared with in-field data. For the study, fully polarimetric data acquired at X-band with a zero-baseline configuration are employed in both scenarios. The displacement results obtained demonstrate the capabilities of GB-SAR sensors for the precise monitoring of ground displacement phenomena.
