Radar Interferometry for Ground Subsidence Monitoring Using Alos Palsar Data

This paper describes the results using data from ALOS and ENVISAT satellites for the purpose of subsidence monitoring over underground coal mine sites in the state of New South Wales, Australia, using the differential interferometric synthetic aperture radar (DInSAR) technique. The quality of the mine subsidence monitoring results is mainly constrained by the noise due to the spatial and tempor...

Interferometric analysis of ALOS/PALSAR data for land subsidence monitoring and crustal deformation detection

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 interfer...

Surface Deformation Analysis Over A Hydrocarbon Reservoir Using InSAR with ALOS-PALSAR Data by Sedar

InSAR has been developed to estimate the temporal change on the surface of Earth by combining multiple SAR images acquired over the same area at different times. In the last two decades, in addition to conventional InSAR, numerous multiple acquisition InSAR techniques have been introduced, including permanent scatterer (PS) (Ferretti et al., 2001) and small baseline subset (SBAS) (Berardino et ...

Anatomy of Subsidence in Tianjin from Time Series InSAR

Groundwater is a major source of fresh water in Tianjin Municipality, China. The average rate of groundwater extraction in this area for the last 20 years fluctuates between 0.6 and 0.8 billion cubic meters per year. As a result, significant subsidence has been observed in Tianjin. In this study, C-band Envisat (Environmental Satellite) ASAR (Advanced Synthetic Aperture Radar) images and L-band...
