A novel displacement measurement method using radio wave for disaster prevention and monitoring has been proposed. In the method, transmitters are attached on multiple measurement points, while, passive sensors, which receive the transmitted radio waves, are set on static points. Comparing phase angles of received radio waves, displacement of measurement points can be estimated simultaneously with high accuracy. Especially, we also developed a modified method calibrating the phase fluctuations of receiving channels. Physical experiment was carried out for verification and performance evaluation. In the experimental results, this method achieved several millimeters stable accuracy for 40 days measurement. |
