The authors have shown in several earlier papers that large ground moving targets can be detected fairly reliably via phase-interferometry in multi-channel Synthetic Aperture Radar (SAR) images of the ground. In a interferometric phase image, all points on the ground nominally appear as a continuum of phase differences while the moving targets appear as discontinuities. By detecting these anoma...

We use Interferometric Synthetic Aperture Radar (InSAR) data to derive continuous maps for three orthogonal components of the co-seismic surface displacement field due to the 1999 Mw7.1 Hector Mine earthquake in southern California. Vertical and horizontal displacements are both predominantly antisymmetric with respect to the fault plane, consistent with predictions of linear elastic models of ...

interferometric synthetic aperture radar (insar) technique is valuable tool in monitoring crustal deformation due to its large spatial coverage and high spatial resolutions. in this paper, the intersiesmic crustal deformation occurred before earthquake on august 2012 in ahar-varzegan located in north-west of iran is studied using persistent scattering interferometry. the psi algorithm used in t...

Through different phases of synthetic aperture radar (SAR) data acquired on dates and/or at satellite imaging locations, the interferometric SAR (InSAR) technique has long been used to map ground deformation or generate global digital elevation model (DEM) (e [...]

The European Space Agency is currently developing Sentinel-1, a constellation of two polar-orbiting C-band radar satellites for operational Synthetic Aperture Radar (SAR) applications. The Sentinel-1 mission is designed for continuous and operational monitoring. The goal is to map the European land mass once every four days in Interferometric Wide Swath (IWS) mode, and the global land surface a...

SUMMARY Subsidence of the land surface is defined as the vertical surface movement due to the removal of subsurface support. This paper presents the differential interferometric synthetic aperture radar (DInSAR) results derived from the data of various SAR satellites, such as ERS-1/2, Radarsat-1 and JERS-1, for subsidence monitoring. One of the limitations of selecting the suitable interferomet...

In this paper we report upon the advances achieved over the past year in the creation of Digital Elevation Models (DEMs) on an operational, commercial basis, using data from two very different radar platforms. STAR3i is an airborne interferometric Synthetic Aperture Radar (SAR), capable of achieving DEMs at a level of detail and accuracy suitable for map scales as large as 1:10,000. A less deta...
