Radar interferometry measurements were used to determine the dynamic response of two bridges. The dynamic excitation was performed via trucks crossing the road bumps placed upon each structure. From the relevant records we then determined the spectral values of the bridges. Detailed mathematical models enabled us to compute the natural frequencies and modes (shapes), and these were subsequently compared with their measured counterparts.
