Space-borne SARs: impact of wavelengths and scan modes on ground motion studies

摘要

Space-borne synthetic aperture radar interferometry (INSAR) is a well-known widely used remote sensing technique to get precise (to the millimeter) surface deformation measurements on large areas (thousands of square kilometers) and high spatial density of measurement points (hundreds per square kilometer). A short review of the INSAR basics is dedicated to the readers who are not INSAR specialists. Then, an analysis of the improvement of ground motion measurement offered by multiple repeated space-borne SAR observations gathered by the new generation of satellites is given and compared with ground-based radar results. Examples from Cosmo-SkyMed and TERRASAR-X are shown and compared with C-band or L-band systems. Finally, the impact of the forthcoming C-band satellites like Sentinel 1 A, B is discussed.View full textDownload full textKeywordssynthetic aperture radar (SAR), INSAR, permanent scatterers, ground deformationRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/19475683.2010.492124
