abstract = "In this paper we analyzes the PALSAR polarimetric signatures and
scattering mechanisms of tropical forest typologies based on
target decomposition. At the representation of polarimetric
signatures, the crosssection of the forest target ({\"{\I}}) was
plotted on a threedimensional graphic as a function of the
orientation angle, ellipticity angle and the intensity of co-polar
components of the radar signal. The analysis of scattering
mechanisms was done by the association of entropy and mean alpha
angle values for each sample, introduced to the bi-dimensional
classification space. Some results can be mentioned: (a) from the
analysis of signatures one can verify that the secondary
succession stages present a relatively high pedestal when compared
to the forested sections; (b) the pixel distribution in the (H)
bi-dimensional space was more frequent at zones 4, 5 and 9 for
forest with or without timber exploitation and for the advanced
secondary succession. This study improves the understanding of the
interaction mechanisms between L-band PALSAR signals and
structural parameters, subsidizing the forest inventory in the
Brazilian Amazon region.",
