Title: METHOD, SYSTEM AND PROGRAM FOR ESTIMATING THE MOVEMENT OF A POTENTIALLY MOVABLE GEOLOGICAL AND/OR CIVIL ENGINEERING STRUCTURE
Abstract:
The invention relates to a method for estimating the movement of a potentially movable geological and/or civil engineering structure (2), the structure (2) being provided with at least one RFID tag (3), and the method using at least one antenna (4) connected to a transceiver terminal (6) and arranged in an independent stable area of the structure (2), close to the RFID tag (3). The method comprises the determination, in a first instant and in a second instant, at the terminal (6), of a first and a second phase of a signal back-scattered by the RFID tag (3), and a processing step for measuring the phase deviation between the first phase and the second phase in order to estimate the movement of the structure (2). The invention also relates to a system (1) and to a computer program for implementing said method.
