چکیده

In the paper we provide an overview of a technique for getting repeat pass interferometric surveys by exploiting the very different ASAR modes: Image Mode, Alternating Polarization and Wide-Swath Mode. We briefly discuss the architecture of the modular processor, able to accept any of the cited modes, together with a DEM (if available, if not a global one like GTOPO30 or ENVI is assumed by default), and we provide hints and refinement achieved after completion the of the validation phase. We provide as well some examples of the final products, achieved in the first year of ENVISAT life, and we highlight the sensor applications in the fields of mapping and differential interferometry.

Combination of Multiple Repeat Orbits of ENVISAT for Mining Deformation Monitoring

In conventional differential radar interferometry (DInSAR), the ground surface displacement can be measured along the line-ofsight. In order to measure the vertical and horizontal displacements DInSAR results of the same deformation derived from at least two different look directions are required. This study utilised the DInSAR results generated from ENVISAT data acquired from three different l...

Monitoring of Sea Ice Dynamic by Means of Ers-envisat Tandem Cross-interferometry

The interest in the monitoring of sea ice masses has increased greatly over the past decades for a variety of reasons. These include: Navigation in northern latitude waters; transportation of petroleum; exploitation of mineral deposits in the Arctic, and the use of icebergs as a source of fresh water. The availability of ERS-Envisat 28minute tandem acquisitions from dedicated campaigns, coverin...

Characterization of Landslide Deformations in Three Gorges Area Using Multiple InSAR Data Stacks

In the areas with steep topography and vulnerable geological condition, landslide deformation monitoring is an important task for risk assessment and management. Differential Synthetic-Aperture Radar interferometry (D-InSAR) and Persistent Scatterer Interferometry (PS-InSAR) are two advanced SAR Interferometry techniques for detection, analysis and monitoring of slow moving landslides. The tech...

Assessment of radar interferometry performance for ground subsidence monitoring due to underground mining

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

On the exploitation of the SBAS Algorithm for the analysis of the deformations detected from the ERS and ENVISAT DInSAR data

We present a Differential Synthetic Aperture Radar Interferometry (DInSAR) technique for generating displacement maps and deformation time-series by exploiting the SAR data acquired by the ERS and ENVISAT/ASAR systems. The proposed approach extends the Small Baseline Subset (SBAS) algorithm and is based on an easy but effective combination of ERS/ERS and ENVISAT/ENVISAT multilook interferograms...
