Remote monitoring of a concrete bridge using PSInSAR

Abstract Structural health monitoring (SHM) can support decision makers in structural integrity management by providing information about occurrence of damage and its evolution time. Recently, due to new Synthetic Aperture Radar (SAR) missions, remote sensing through active satellites provides a promising methodology capable infrastructure assets. This paper investigates the use Multi‐Temporal Interferometry (MT‐InSAR) processing monitor bridges. The full interferometry chain is applied using Sentinel‐1 synthetic aperture radar data combination open‐source routines from Sentinel Application Platform (SNAP) Stanford Method for Persistent Scatterers (StaMPS). Displacement time‐histories are derived single look complex products employing Scatterer (PSInSAR) technique. PS‐InSAR technique study behavior concrete bridge located over Oglio river Isola Dovarese, Italy, on which also GNSS receivers installed. then used validate measurements. effects results number SAR images as well target structure investigated.
