“…Os ângulos de elipticidade de 0º e + 45º, por exemplo, representam as polarizações linear e circular, respectivamente (Figura 1a). Com χ = 0 os ângulos de orientação de 0º e 90º representam polarização horizontal e vertical (EVANS et al, 1988;SANTOS et al, 2009) (Figura 1b). Aliado a isso, a altura pedestal mínima, representada no gráfico da figura 1b, indica a parte da componente não polarizada do espalhamento, estando relacionada ao grau de polarização da onda espalhada (EVANS et al, 1988).…”

“…The latter is the current route of scientific development to improve the understanding from the interaction among SAR polarimetric signals and structural parameters from the tropical forest environmental, allowing the identification of scattering mechanisms using differences in the polarization response (Figure 3) for mapping and forest inventory purposes. Taking into account the representation in a plane (-90º< ψ < +90º), the highest values of intensity for an ellipticity angle at 0º and an orientation angle at 0º, the polarization is horizontally oriented (EVANS et al, 1988;MC NAIRN et al 2002). For the primary forest this dependence is the result of randomness of the structure with horizontal (high values around ψ = 0° (horizontal polarization) and χ = 0° (linear polarization)) and vertical components (ψ = ± 90° (vertical polarization) and χ = 0 (linear polarization)).…”
