The detection of active rock glacier and the quantification of the observed surface movement as well as its temporal change using the D-InSAR method are presented. An average deformation rate of -7.7 mm/35 days in the radar lineof-sight, in the summer of 1992, was estimated. Whereas, the corresponding geodetic measurement, vertical component of 3D flow velocity, was about –8.0 mm/35 days. Addit...

In this paper the selected interferometric studies of subsidence caused by underground mining are discussed. Despite the common limitations the traditional single-polarization InSAR technique is already proved its high potential in this application. Today, the determination of the areas of affected by terrain deformation risks becomes one of the most promising applications for operational use o...

The problem of phase unwrapping in two dimensions has been studied extensively in the past two decades, but the three-dimensional (3D) problem has so far received relatively little attention. We develop here a theoretical framework for 3D phase unwrapping and also describe two algorithms for implementation, both of which can be applied to synthetic aperture radar interferometry (InSAR) time ser...

The reasons were clear: before the InSAR era crustal deformation was measured using very time-consuming, ground based methods, as leveling, triangulation, trilateration; all requiring costly networks and measurement campaigns. The same was true for the GPS technique, appeared only few years before. SAR interferometry made things simpler and cheaper, although with some limitations; probably the ...

Next-generation interferometric synthetic aperture radar (InSAR) systems may provide the basis for establishing an earthquake-forecasting capability within a twenty-year time frame. Such systems would need to provide data with fine temporal resolution, so the system architecture would need to allow for wide-area coverage in order to minimize the effective interferometric repeat time. This paper...

The atmospheric artifacts in interferometric synthetic aperture radar (InSAR) measurements are a large error source in accurately estimating terrain deformation signals [1]. For example, the large magnitude, high spatial frequency atmospheric bubbles can easily be misinterpreted as deformation phenomena [2, 3]. Various InSAR time series techniques, such as the Permanent Scatterer (PS) and Small...

Correlation between Interferometric Synthetic Aperture Radar (InSAR) pairs is essential for accurate interferometric phase estimation and digital elevation model (DEM) reconstruction. In this paper, a SAR simulator capable of generating Rayleigh and K-distributed terrain clutter and estimating correlation between InSAR passes will be presented. Furthermore, this simulator will be used to study ...

We investigate the potential of combined features of aerial images and high-resolution interferometric SAR (InSAR) data for building detection in urban areas. It is shown that completeness and correctness may be increased if we integrate both InSAR double-bounce lines and 3D lines of stereo data in addition to building hints of a single optical orthophoto. In order to exploit context informatio...

Differential SAR Interferometry (D-InSAR) is an effective tool in monitoring land subsidence because of its greater coverage area and better resolution of height change. A series of Japanese Earth Resources Satallite-1 (JERS-1) images from 1992 to 1998 has been used in monitoring the mine subsidence in the test site of this study, one of the important coal mining areas in China. D-InSAR procedu...

InSAR signal delays due to the varying atmospheric refractivity are a potential data source to improve weather models [1]. Especially with the launch of the new Sentinel-1 satellites, which increases data coverage, latency and accessibility, it may become possible to operationalize the assimilation of differential integrated refractivity (DIR) values in numerical weather models. Although studie...
