RotoSAR for monitoring bridges

RotoSAR is a ground-based SAR (Synthetic Aperture Radar) able to detect the three displacement components of large structures like bridge, towers, dams, and buildings. In this paper the RotoSAR theory has been applied to a specific case of engineering interest: the static testing of bridges. An in-field test of the technique and the prototype has been performed during the static test of a bridge in Florence (Italy).
