- Data acquired through a Real Aperture Radar interferometer aimed at monitoring a tall tower and its guys are here analysed. The acquisition of temporal samples of interferometric phase, corresponding to different parts of the tower, are used to estimate main vibration frequencies and modal shapes of the tower. Guys have been also monitored to verify the possibility to retrieve their tension force using the taut string approximation. The study confirmed the potential of this technique considering also that an analogous monitoring carried out with conventional contact sensors would be unadvisable due to its high costs and the strong electromagnetic noise of this environment.
