Monitoring structures with FastGBSAR

Abstract

Monitoring ground deformation and structural movements is an important task in order to prevent hazardous and harmful situations for the population. MetaSensing's FastGBSAR (Fast Ground-Based Synthetic Aperture Radar) is a novel sensor system, which allows the monitoring of deformation and vibration of natural and man-made structures. It is a radar sensor based on the FM-CW (Frequency Modulated Continuous Wave) technology and it is available in different configurations depending on the application: single polarization, interferometric or polarimetric configuration. It can operate in Real Aperture Radar or Synthetic Aperture Radar mode allowing the monitoring of vibration or deformation of structures respectively. This paper describes three examples of application of the FastGBSAR to different sites in China providing examples of its usage for monitoring a dam, a railway bridge and an instable slope.
