I
nterferometric methods are drivers of the recent exponential growth in the use of synthetic aperture radar (SAR)
for monitoring both natural and anthropogenic hazards.
Since the first use of interferometric SAR (InSAR) in the late
1990s to detect deformations associated with earthquakes
and volcanoes, important developments have improved
sensor performance and data-processing capabilities for the
extraction of information of interest in geophysical appli-
cations. Here, we describe the improvements that have enabled the 3D reconstruction and monitoring of buildings,
with reference to their protection against and prevention of
risks. We focus on buildings affected by systematic displacements related to natural hazards-specifically, landslides.
We address the straightforward use of InSAR methods in
the detection and characterization of the hazard as well as
in higher-level exploitation for geotechnical and structural
studies and, more generally, vulnerability analysis.
DEVELOPMENT OF SAR
INTERFEROMETRIC APPROACHES
Satellite SAR is a unique instrument for Earth observation
[1]: it is capable of sensing Earth's surface with spatial details
comparable to those of very-high-resolution (VHR) optical
cameras but with the advantages of all-weather and all-time

at Landslide Risk With SAR
