Abstract: A method and system are described for measuring displacements and vibrations of an object/structure. The method includes transmission of at least one radar wave by a single radar device positioned at a predefined distance from a receiver device applied on the object/structure, reception, by the radar device, of a complex signal consisting of the sum of the signal reflected from said receiver device and of one or more interfering signals generated by one or more corresponding targets substantially stationary and substantially positioned at the same distance from the radar device, separation of the interfering signals from the reflected signal. The separation includes calibration by induction, for a pre-determined period of time, of a vibrational motion having a known frequency and duration in the receiver device, which consequently operates as a calibration device, for obtaining an estimated value of the interfering signals.
