This work presents a new approach for three-dimensional (3D) coastal deformation simulation using differential synthetic aperture interferometry (DInSAR). In doing so, conventional InSAR procedures are implemented to three repeat passes of RADARSAT-1 SAR fine mode data (F1). Further, the DInSAR method is implemented with the phase unwrapping technique. Consequently, DInSAR is used to eliminate ...

The paper is focused on Digital Elevation Model (DEM) reconstruction from differential interferometry synthetic aperture radar (DInSAR). In doing so, conventional DInSAR procedures are implemented to three repeat passes of RADARSAT-1 SAR fine mode data (F1). Further, the multichannel MAP height estimator is implemented with phase unwrapping technique. Consequently, the multichannel MAP height e...

A quantitative deformation monitoring using the differential interferometric SAR (DInSAR) technique may be achieved when multiple DInSAR observations and suitable modelling and analysis tools are employed. The paper begins with a description of the main characteristics of the DInSAR data. Then, it discusses a new modelling and filtering strategy, which takes advantage of the specific properties...

This paper introduces a new method for three-dimensional (3D) coastal geomorphology reconstruction using differential synthetic aperture interferometry (DInSAR). The new method is based on an integration between fuzzy B-spline algorithm and DInSAR method. DInSAR algorithm is involved two parts: (i) 3D map simulation which is based on interferogram simulation and (ii) satellite orbit parameters....

Differential Synthetic Aperture Radar Interferometry (DInSAR) is a microwave remote sensing technique that allows us to investigate surface deformation phenomena with a centimeter to millimeter accuracy with a large spatial coverage capability. Firstly applied to investigate single deformation events, the DInSAR algorithms have further been developed to analyze the temporal evolution of the det...

This work presents the first experimental demonstration of the virtual bandwidth synthetic aperture radar (VB-SAR) imaging scheme. VB-SAR is a newly-developed subsurface imaging technique which, in stark contrast to traditional close-proximity ground penetrating radar (GPR) schemes, promises imaging from remote standoff platforms such as aircraft and satellites. It specifically exploits the dif...

This paper presents an advanced DInSAR-GIS technique developed by the Cartographic Institute of Catalonia (ICC) for the generation of precise terrain deformation maps using data acquired by satellite platforms. These radar systems, known as Synthetic Aperture Radars (SAR), allow obtaining terrain reflectivity images, which are processed by means of DInSAR algorithms for monitoring ground stabil...

This paper reports the progress of the ongoing ESA CAT-1 project (ID 1078). Radar interferometry (InSAR) has been used together with GIS (Geographic Information System) technique to monitor ground subsidence due to underground mining in a test site around the Appin township, southwest of Sydney, Australia. Various digital elevation models (DEMs) are assessed using elevation profiles from ground...

Differential (D) and persistent scatterer (PS) interferometric synthetic aperture radar (InSAR) (DInSAR and PSInSAR) techniques are arguably the most cost effective and efficient methods today for ground surface deformation monitoring since their invention in the last quarter of the twentieth century. They overcome the limitations of traditional methods of deformation monitoring with regards to...

In this paper we show a new technique, based on the elastic theory, to efficiently produce an estimate of threedimensional surface displacement maps by integrating sparse Global Position System (GPS) measurements of deformations and Differential Interferometric Synthetic Aperture Radar (DInSAR) maps of movements of the Earth’s surface. We propose a linear matrix equation which accounts for both...
