                         typologies based on target decomposition. The fundamentals of 
                         polarimetric theory related to both SAR topics under development 
                         are summarized. For representation of polarimetric signatures, the 
                         cross-section of the forest target (0) was plotted on a 
                         bi-dimensional 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 of each 
                         sample, plotted in a bi-dimensional classification space. This 
                         study improves the understanding of the interaction mechanisms 
                         between L-band P ALSAR signals and structural parameters,
