Space-Borne and Ground-Based InSAR Data Integration: The Åknes Test Site
This work concerns a proposal of the integration of InSAR (Interferometric Synthetic Aperture Radar) data acquired by ground-based (GB) and satellite platforms. The selected test site is the Åknes rockslide, which affects the western Norwegian coast. The availability of GB-InSAR and satellite InSAR data and the accessibility of a wide literature make the landslide suitable for testing the propo...
متن کاملBuilding Recognition Based on Airborne and Space Borne Insar Data
Because of its independence of time of day and its all weather capability, synthetic aperture radar (SAR) has become a key remote sensing technique in the last decades. In the past, spatial resolution of space borne SAR systems was rather coarse, so the exploitation of building signature and even the reconstruction of buildings in dense urban areas based on InSAR data was restricted to commerci...
متن کاملDecrypting geophysical signals at Stromboli Volcano (Italy): Integration of seismic and Ground-Based InSAR displacement data
We present the integration of seismic and Ground-Based Interferometric Synthetic Aperture Radar system (GBInSAR) displacement data at Stromboli Volcano. Ground deformation in the area of summit vents is positively correlated with both seismic tremor amplitude and cumulative amplitudes of very long period (VLP) signals associated with Strombolian explosions. Changes in VLP amplitudes precede by ...
متن کاملShifts in the eruptive styles at Stromboli in 2010–2014 revealed by ground-based InSAR data
Ground-Based Interferometric Synthetic Aperture Radar (GBInSAR) is an efficient technique for capturing short, subtle episodes of conduit pressurization in open vent volcanoes like Stromboli (Italy), because it can detect very shallow magma storage, which is difficult to identify using other methods. This technique allows the user to choose the optimal radar location for measuring the most sign...
متن کاملInSAR Phase Unwrapping by Transforming Sparce Data into a Regular Space
Phase unwrapping is one of the most important parts of InSAR techniques. In order to estimate the grand surface displacements, interferomtric phases modulated between 0 to 2π must be unwrapped. Based on the use of either the conventional method or persistent scatterer (PS), phases will be spread both regularly and irregularly. The phases of PSs can be unwrapped by reducing phases into a regular...
