Reflectometric system and method for measuring vibrations or deformations of objects/structures

A reflectometric system and method for the measurement of deformations and/or vibrations of an object/structure includes a radar device for transmitting a radar signal to at least one target associated with the object/structure, the target being a vibrating target with a mechanical vibration mechanism equipped with an electric motor group to generate a self-induced motion with respect to the object/structure. The at least one vibrating target vibrating with its own frequency of induced vibration, modulating the radar signal at least on the basis of its own frequency of induced vibration to generate a return signal received by the radar device as part of a complex signal. The complex signal is processed to determine an identification signal of each vibrating target using its own frequency of induced vibration; the measurement of deformations and/or vibrations determined for each vibrating target on the basis of a phase value extracted from the identification signal.
