摘要

An analysis of the displacement along a funicular in Switzerland was performed using ERS-1/2 SAR data. An initial interferometric point target analysis was performed with images acquired before the spring of 1999 and excluding all winter acquisitions with snow cover. The profile of the displacement rate along the funicular shows maximum values of about 1.5 cm/year in the satellite line-of-sight direction, with negligible displacements near the lower and upper stations. After the spring of 1999, when displacements of several dm's occurred because of heavy rainfall, the analysis was continued on single interferograms on the previously identified point targets. With a series of interferograms with large baselines we could analyze the displacements along parts of the funicular during 1999 and 2000.
