2d Phase-Based RFID Localization for On-Site Landslide Monitoring
Passive Radio-Frequency Identification (RFID), used recently to monitor landslide displacement at a high spatio-temporal resolution, was used to measure only 1D displacement. This study demonstrates the ability to track 2D displacements, using an array of antennas connected to an RFID interrogator. Ten tags were deployed on a landslide for 11 months and 2D relative localization was performed using a Phase-ofArrival approach. The centimeter-scale accuracy of this technique was confirmed experimentally and theoretically, by developing a measurement model that includes multipath interference. A period of activity was monitored through both RFID and microseismicity measurements, investigating the correlation between soil displacement and seismic activity. This study confirms that 2D landslide displacement tracking with RFID is feasible at relatively low instrumental and maintenance cost
