Abstract

Advanced InSAR techniques in landslide monitoring.A b s t r a c t. In recent years, there has been a rapid development of SAR acquisition techniques and all new satellite radar missions are equipped with SAR devices allowing beam steering. This paper presents results of experimental application of TerraSAR-X in ultra-high resolution SpotLight and Staring SpotLight modes for the area of the Just landslide in the Rożnow lake area. Another analyzed example was to use data of the medium resolution Sentinel-1 data acquired in the TOPS mode for the Huciska and Zapadle landslides in Szymbark. In this case, a network of 12 radar reflectors (corner reflectors) was installed to make the results independent of vegetation conditions on landslides. This study presents preliminary results of measurements and discusses the potential of applications and directions of further work.
