dc.descriptionABSTRACT -The widespread occurrence of clouds over the Amazon basin for most of the year makes radar data particularly interesting for mapping the vegetative cover and for monitoring deforestation and biophysical parameters in general. In this study, we presented the preliminary results of an airborne SAR campaign over two sites in the States of Rondônia and Amazonas. The SAR instrument, owned and operated by the Amazon Protection System (SIPAM), acquired L-band data at vv polarization mode and 6m spatial resolution. At this configuration, it was possible to detect clear cut areas with a variety of sizes and shapes, confirming the high precision and accuracy of the SAR-SIPAM instrument. In addition, the integration of the radar data with MOD13 reflectance images suggests a potential synergism between SAR and optical datasets, which can be used, among others, for ground truth purposes of deforestation detection based on moderate resolution optical imagery.
