Ground deformation analysis along island subway line by fusing time-series InSAR and LiDAR techniques

Multiscale InSAR Time Series (MInTS) analysis of surface deformation

[1] We present a new approach to extracting spatially and temporally continuous ground deformation fields from interferometric synthetic aperture radar (InSAR) data. We focus on unwrapped interferograms from a single viewing geometry, estimating ground deformation along the line-of-sight. Our approach is based on a wavelet decomposition in space and a general parametrization in time. We refer t...

Ground Deformation Mapping Using Insar

SAR interferometric data can be used for extracting three dimensional information of the earth’s surface by using the phase part of the radar signal. In this study, available SAR interferometric data acquired before and after the Marmara earthquake of 1999 and provided by ESA were used for mapping the ground deformation in the satellite line of sight (LOS) in the Izmit province. The interferome...
