Abstract
This paper aims to demonstrate that radar-based remote
sensing techniques can be as effective as the conventional
geotechnical ones for the detection and monitoring of well
suited areas. Many of the high mountain landslides are
vegetated areas that decorrelate faster at X-band. As in these
scenarios the number of coherent scatterers is low and, in
addition, the area of interest is usually small, the processing
can be benefited of the usage of high-resolution data. This
will maximize the chances of detecting persistent scatters
coming from both natural targets and man-made structures.
The high resolution Spotlight mode of TerraSAR-X is thus
the perfect choice as it offers a fine resolution. On the other
hand, its 11 days of revisit time and X-band carrier allows
the monitoring of small variations in the landslide trend and
deal with its variable dynamics.
