Interferometric analysis of ALOS/PALSAR data for land subsidence monitoring and crustal deformation detection
نویسندگان
چکیده
We analyzed ALOS PALSAR interferometric data pairs from Sendai Plain, Japan, along the Pacific Ocean. Continuous fringe patterns were extracted from the data pair of which perpendicular baseline distance is more than 2000 m. Most of the interferograms generated in this study show fringe features that are independent from actual surface deformation. Some features are common to different interferograms produced by combining related data. We compared these fringe patterns with the simultaneously observed AVNIR-2 images. The cloud distribution patterns on the AVNIR-2 images are possible to explain interferometric fringe pattern as the atmospheric effect.
