摘要

桥梁挠度和适用性评估对桥梁结构状况和基础设施维护至关重要。在这项研究中，我们的目标是利用x波段cosmos - skymed和c波段Sentinel-1 A/B SAR数据估计桥梁的高分辨率位移。我们对丽水地区的巨北山大桥和斗山大桥进行了多时相干涉分析。除桥梁位移外，还通过估算DEM误差来修正散射体的地理定位误差。

High-resolution bridge displacement monitoring using Time-seriesPS- InSAR technique

Assessment of bridge deflection and serviceability is essential for structural condition and infrastructure maintenance. In this study, we aim to estimate the high-resolution displacements of bridges using X-band Cosmo-SkyMed and C-band Sentinel-1 A/B SAR data. We applied multi-temporal Interferometric analysis to Geobuksan bridge and Dolsan Bridge in the Yeosu region. In addition to the bridge displacements, the geolocation error of scatterers were corrected by estimating DEM error.
