Interferometric Measurements of Bridges Displacements and Scattering Mechanisms
The paper aims at bridges displacement evaluation. Sentinel-1 high resolution SAR data provides with detailed images of selected bridges. Two types of bridge design were selected: suspension bridges as rather flexible objects, and a girder bridge with its stiffness as a more stationary target. Vertical displacements of suspension bridges reach up to 12,6 cm for 12-days time interval. A girder bridge crossing a quiet river shows small shifts between its parts in the phase image of its upper surface, and in addition in the phase image of its underneath due to triple-bounce scattering mechanism and almost windless weather. Vertical displacements of 9 mm were registered.
