L-band SAR interferometry has shown a great potential for the efficient mapping and monitoring of mass movements in alpine environments. Satellite SAR data at L-band are currently being collected among others by ALOS-2 PALSAR-2 since 2014 and SAOCOM-1 since 2018. In addition, we are acquiring high-resolution L-band SAR imagery with a car-borne system. These different L-band sensors collect data with various time intervals and viewing geometries, which need to be integrated to be effectively exploited by users. In this paper we present our first experiments in this respect at three sites in Italy and Switzerland, characterized by slope deformations of different type, size and rate of movement. For all sites, we present the L-band results of the three sensors, emphasizing their complementarity and peculiarities.

Abstract
L-band SAR interferometry has shown a great potential for the efficient mapping and monitoring of mass movements in alpine environments. Satellite SAR data at L-band are currently being collected among others by ALOS-2 PALSAR-2 since 2014 and SAOCOM-1 since 2018. In addition, we are acquiring high-resolution L-band SAR imagery with a car-borne system. These different L-band sensors collect data with various time intervals and viewing geometries, which need to be integrated to be effectively exploited by users. In this paper we present our first experiments in this respect at three sites in Italy and Switzerland, characterized by slope deformations of different type, size and rate of movement. For all sites, we present the L-band results of the three sensors, emphasizing their complementarity and peculiarities.
