abstract = "This study shows the use of dual-polarized L-band Synthetic
Aperture Radar (SAR) data acquired by the Advanced Land Observing
Satellite (ALOS) Phased Array type L-band Synthetic Aperture Radar
sensor (PALSAR) system for differentiation between primary forest
and new deforestation fronts. Results showed that the new
deforested areas are not unequivocally detected in either of the
single bands individually. Although most of the recent
deforestation appears brighter than mature forests in the HH band,
the identification of new deforestation using only this band
depends on the stage of the clearing process. Then, the
contribution of the HV band through a normalized difference index
(NDI) is important for detection of the new deforested fronts.
Results indicate that the method can be used as the basis for an
operational programme to monitor deforestation in the Brazilian
Amazonia.",
