Synthetic aperture radar interferometry, InSAR, is a novel remote sensing technique to measure earth surface deformation. It is capable of obtaining dense information related to the deformation of a large area efficiently, economically and effectively. Therefore, InSAR is a promising technology for monitoring the earth surface deformation related to some natural hazardous events, such as earthq...
The aim of this study is to use the original and other ancillary derived features extracted from multitemporal spaceborne interferometric synthetic aperture radar (InSAR) data sets for land cover mapping. For the actual land cover mapping, supervised (statistical maximum likelihood classification) and unsupervised (isodata clustering) classifications have been performed using a) the original In...
Interferometric synthetic aperture radar (InSAR) imaging is a recently developed geodetic technique capable of measuring ground-surface deformation with centimeter to subcentimeter vertical precision and spatial resolution of tens-of-meter over a relatively large region (~10 km). The spatial distribution of surface deformation data, derived from InSAR images, enables the construction of detaile...
Interferometric synthetic aperture radar (InSAR) processing relies on phase unwrapping to convert interferometric phase to topographic height. Phase unwrapping is a di cult non-linear process that is still the subject of on-going research. Rather than processing the complete phase image to extract a digital elevation model (DEM), we use existing coarse DEMs as an integral part of the InSAR algo...
In this paper, we present the results of several case studies using InSAR techniques from high resolution RADARSAT to monitor active landslides triggered by earthquakes and other geomorphic processes. Our results have shown that our InSAR results were used that facilitate mitigation efforts along strategic transportation and energy corridors as well as reconstruction efforts in earthquake damag...
a r t i c l e i n f o Keywords: Atmosphere Tropospheric noise Corrections Phase-based Spectrometers Weather models InSAR State-of-the-art TRAIN Correcting for tropospheric delays is one of the largest challenges facing the interferometric synthetic aperture radar (InSAR) community. Spatial and temporal variations in temperature, pressure, and relative humidity create tropospheric signals in InS...
Interferometric synthetic aperture radar (InSAR) has become a broad field encompassing the use of both airborne and spaceborne sensors operating at a range of wavelengths and resolutions. This paper derives general conclusions from experiences at the Remote Sensing Laboratories of the University of Zürich with a variety of airborne and spaceborne InSAR sensors. Results from multiple systems ope...
Beijing is one of the most water-stressed cities in the world. Due to over-exploitation of groundwater, the Beijing region has been suffering from land subsidence since 1935. In this study, the Small Baseline InSAR technique has been employed to process Envisat ASAR images acquired between 2003 and 2010 and TerraSAR-X stripmap images collected from 2010 to 2011 to investigate land subsidence in...
