摘要：The paper presents preliminary results of research on a possibility of applying SAR interferometry to the assessment of landslides in the Polish part of the Carpathians. For the purpose of this study,the NW edge of Nowy Sącz basin has been chosen. Applications of InSAR (SAR Interferometry) to the Carpathians is difficult due to the rough topography,vegetation,and prolonged snow cover. Such problems were overcome by applying PSInSAR (Persistent Scatterers SAR Interferometry) which utilizes long time series of SAR data. In the present case,a set of Persistent Scatterers was collected by processing a stack of 55 ERS-1/2 SAR scenes using Delft University of Technology’s implementation of the PSI method. Some 145 highly coherent PS points were obtained;they provide evidence of a landsliding movement. The most reliable points were then used in a quantitative cartographic study to assess the movement along the slope. Analysis of landslide dynamics was carried out for the study area whereby a landslide in Podegrodzie,progressing at a rate of 72.9 mm/year was documented. The preliminary results are very promising for the development of PSInSAR methodology to study landslides in Poland.
