Radar interferometry with Sarscape software
Hadji Sahraoui, O. ... [et al.]
The availability of technical public domain software is important for a fast acceptance and integration of a technique in other disciplines, enabling scientists to gain experience with new techniques at low cost. Synthetic aperture radar (SAR) interferometry (InSAR) is an imaging technique for measuring the topography of a surface, its changes over time, and other changes in the detailed characteristics of the surface. By exploiting the phase of the coherent radar signal, interferometry has transformed radar remote sensing from a largely interpretive science to a quantitative tool, with applications in cartography, geodesy, land cover characterization, and natural hazards. Radar interferometry using freely available software has matured to a stage in which data from different sensors can be routinely processed to interferometric products. SARscape is one of the latest contributions to public-domain radar interferometry software. It is designed as a specialized software package for processing of SAR/InSAR data, and perfectly complements ENVI's functionality for analyzing and visualizing remote sensing data of any kind. More specifically, SARscape for ENVI is a modular set of ENVI (Environment for Visualizing Images) functions for processing of spaceborne remote sensing data from Synthetic Aperture Radar sensors. Currently, the systems ERS-1/2, JERS-1, RADARSAT-1 and ENVISAT ASAR are fully supported by SARscape for ENVI. In this paper, we present the feasibility of the SARscape radar interferometric software to create ERS interferometric products such as DEMs and deformation maps. A stepwise description of the creation of an ERS DEM of the Oran area in Algeria is presented.
