Study on Three Dimensional Real-Time Measurement Method of Displacement Using a Radio Wave

Language：Japanese

Numerous locations in Japan are potentially prone to slope failure. To deal with slope failure, it is crucial to establish a measurement technology that can quickly provide necessary data for adopting effective measures. In this study, the method of measuring slope displacements using a radio wave is explored and its validity examined. The use of a radio wave has lots of advantages : to allow the extensive area-wide tracking of three dimensional deformations in real-time, and to allow remote measurements with high accuracies and precisions. We plan to enhance the practicality of this method by offering more slope monitoring application examples.

Long Term Monitoring for Disaster Prevention by Radio Phase Displacement : An Experimental Result

Language：English Publisher：The Institute of Electronics, Information and Communication Engineers

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.
