The Real-Aperture-Radar (RAR) is an interesting terrestrial remote sensing device, which can be used to monitor the vibration characteristics of buildings, structures and infrastructures, see Luzi et al. (2012) and (2014). It offers three interesting vibration monitoring capabilities:

  • a very high sensitivity to displacements;
  • the capability to sample the vibrations in time at high frequencies;
  • non-contact and easy-to-make remote sensing measurements.

These are unmatched capabilities from the point of view of geomatics, which can be exploited to open new applications. This technique can be used in some specific fields such as Civil Engineering (Luzi et al., 2017), Structural Engineering, Seismological Engineering, etc. The activity of our group include:

  1. Developing and integrating new RAR sensors, e.g. see Luzi et al. (2017b).
  2. Developing new vibration monitoring applications related to buildings, towers, bridges, viaducts, etc.
