RADARES IMAGEADORES NAS GEOCIÊNCIAS: ESTADO DA ARTE E PERSPECTIVAS

Abstract

Results from more than a decade of orbital Synthetic Aperture Radars (SARs) applied to Geoscience, mainly in the moist tropics, have shown that the technology has provided useful information, mainly derived through qualitative approaches. Images of amplitude (monoscopic and stereoscopic analysis, digital integrated products and textural classification) have been used for terrain mapping. The paper discusses current application trends for Cartography and Geology based on conventional radar data (one frequency, one polarization) and perspectives driven by a more quantitative approach with the advent of multipolarized, polarimetric and interferometric imaging radars.
