ResumoSAR images have been successfully used for geological applications in the moist environments of Brazil. However, for semi-arid environment researches dealing with radar are still rare. The Cu-rich district of Curaçá Valley (Ba) is characterized by a flat topography with residual soils and low to moderate Caatinga vegetation cover. Geologically, the Valley is part of the Salvador-Curaçá belt, a Paleoproterozoic N-S trending, granulite-amphibolite belt in the São Francisco Craton. The lithological units are grouped as Archean gneisses and granulites interbedded with ferruginous rocks, quartzites, amphibolites, mafic-ultramafic intrusives and Upper Proterozoic marbles/limestones, schists, and phyllites. The objective of the investigation was to evaluate the influence of micro-topography on RADARSAT-1 and PALSAR responses as an aid to discriminating surficial geologic units. The images were acquired under distinct look-azimuth (ascending, descending passes) and variable incidence. Four RADARSAT-1 (F2 ascending, S2 and S7 ascending, S7 descending) and one PALSAR (FBD, descending) images were used. The relationship between sigma nought (σº) and rms-heights (hrms) and correlation-length (Lc), revealed that the use of micro-topography for characterization of geological surfaces is limited, given by a weak to moderate linear correlation (R2² ≤ 0.50) for both SAR data. For RADARSAT-1, the dependence of σº on hrms and Lc increased from steeper to shallower incidence independently of the look-azimuth. For PALSAR, the maximum value of R2² (0.51) for hrms and Lc was obtained for cross-pol (L-HV). Volume scattering related to the vegetation with green foliage probably contributed to this performance.
