In the past few years differential synthetic aperture radar (SAR) interferometry (DInSAR) from ground‐based installations has provided multi‐temporal surface deformation maps of landslides. Experimental data have demonstrated its effectiveness for remote monitoring of terrain slopes and as an early‐warning system to assess the risk of rapid landslides. Following a brief description of the principles of operation of SAR interferometry, the use of a portable ground‐based radar to survey the large active landslide of Tessina, near Belluno in north‐eastern Italy, is described. This landslide was monitored for the first time in 2000. The current experimental study, carried out with a different instrumental configuration, confirms the effectiveness of this technique for estimating the evolution of landslide movements.

Abstract
In the past few years differential synthetic aperture radar (SAR) interferometry (DInSAR) from ground‐based installations has provided multi‐temporal surface deformation maps of landslides. Experimental data have demonstrated its effectiveness for remote monitoring of terrain slopes and as an early‐warning system to assess the risk of rapid landslides. Following a brief description of the principles of operation of SAR interferometry, the use of a portable ground‐based radar to survey the large active landslide of Tessina, near Belluno in north‐eastern Italy, is described. This landslide was monitored for the first time in 2000. The current experimental study, carried out with a different instrumental configuration, confirms the effectiveness of this technique for estimating the evolution of landslide movements.
