Monitoring of displacements with ground-based microwave interferometry: IBIS-S and IBIS-L
TLDR
In this paper, the principles of the microwave interferometer IBIS are presented, as well as its advantages and disadvantages compared to common monitoring techniques, and three applications are presented: the use of IBIS-S for dynamic monitoring of a chimney, the long-term operation of IBMIS-L as part of a “Volcano Fast Response System” (VFRS) on an active volcano.Abstract:
Abstract One fundamental component of early warning systems for natural hazards is displacement monitoring. Spaceborne SAR Interferometry has proven to be a powerful remote sensing tool for this task. Lately new ground-based SAR instruments are available. Their application field is wide and they combine high resolution and accuracy with the classical benefits of remote sensing techniques. Here, the principles of the microwave interferometer IBIS are presented, as well as its advantages and disadvantages compared to common monitoring techniques. IBIS can be operated in two modes: IBIS-S is a microwave interferometer capable of high frequency displacement monitoring of buildings and structures (up to 200 Hz); IBIS-L is a ground-based SAR for long-term displacement monitoring of buildings and natural phenomena as landslides, glaciers, etc. Exemplary three applications are presented: the use of IBIS-S for dynamic monitoring of a chimney; the use of IBIS-L for displacement monitoring in an active quarry and the long-term operation of IBIS-L as part of a “Volcano Fast Response System” (VFRS) on an active volcano.read more

Vision-based system identification technique for building structures using a motion capture system
TL;DR: In this article, a vision-based system identification (SI) technique for building structures by using a motion capture system (MCS) is presented. But, the MCS with outstanding capabilities for dynamic response measurements can provide gage-free measurements of vibrations through the convenient installation of multiple markers.

Microwave interferometers for non-contact vibration measurements on large structures
TL;DR: In this paper, a non-contact vibration measuring system based on a microwave interferometer similar to those used to detect the presence of people in monitored areas is described. But unlike most commercially available far-field noncontact vibration sensors, this system offers other advantages including low cost, quick set-up time, a wide frequency range of response and portability.
