This paper describes two novel remote sensing techniques based on radar sensors, respectively the
Synthetic Aperture Radar (SAR) and the Real Aperture Radar (RAR), and some applications to
relevant geotechnical problems with the aim to demonstrate the outcomes these types of sensors can
provide. The case studies here described show how the SAR technique can provide useful
information to interpret landslides’ kinematics and how the RAR can be used to monitor dam
displacements and tunnels’ convergences
