%X This paper presents an assessment of the use of the ALOS PALSAR, Kyoto and Carbon Initiative and ScanSAR data for the Brazilian Forest Monitoring Program. Using deforestation polygons mapped by INPEs DETER project, PALSAR ScanSAR multi-temporal images were analyzed for the detection of deforestation patterns. The obtained result shows that approximately 50% of the polygons could be detected by PALSAR ScanSAR images for areas larger than two square kilometers. It is notable that these deforestation patterns were detectable before the DETER Alerts. A multi-temporal approach is proposed to efficiently process the ScanSAR data, enhance their quality, and generate, in an automated way, recent deforestation. It consists of a radiometric re-calibration of the slant range gamma nought input data, a multi-temporal co-registration and speckle filtering, a terrain geocoding, a multi-temporal anisotropic non-linear diffusion filtering, and finally, an automated classification compatible with the PRODES clear mapping. Considering the importance and extent of the Amazon forest and its cloud cover conditions, the PALSAR ScanSAR-based product is now under evaluation for integration within the Forest Monitoring Program. Furthermore, assimilation of the proposed product into the operation of the DETER project is a first step within the INPEs Forest Monitoring Program toward the integration of additional SAR (Synthetic Aperture Radar) products based on the forthcoming planned Brazilian sensors, such as MAPSAR and CBERS-7.
