Abstract
The multli-frequency and multi-polarization Shuttle Imaging Radar (SIR-CIX Synthetic Aperture Radar (SAR] data collocted in 1934 aboard two flights of the Shuttle Endeavour constitutes a milestone in imeging of deserts from space, The data are here used to explore the eastern Sahara, including lithological and struclurat mapping, gcomorphological studies, and min- eratl exploration. The sm-oix-sAn images in this environment are generally found lo be (1) less usoful for lithological mapping than orbital visible and necr infrared (VNIR) images, except whcre rock types weather differently lo produce varying roughness lovels; (2) saperior to orbilal VNIR images for structural mopping in areds of subdued telicf or where ruclures are partially covered by dry sand, as well as in octonically active mountainous derrains: (3) superior to tal NIH 1age for mapping surf face und sub-surface gromorphologiral Joctares guch as palco-channelst Ond (4) jul in delineai 1g geoloyic rontrols on mineral deposits, but ferk o Vif itnages for direct identificalion of these.
