Abstract EN
The morphology of vegetation greatly impacts propagation of polarized electromagnetic wave.
In order to validate this phenomenon, the mathematical relation between the differential propagation constant of forest vegetation and of its polarized echo is quantitatively derived by using backscattering power profile.
The fluctuation of differential propagation constant with frequency is analyzed by combining the morphological characteristics of vegetation.
The accurate copolarized data of 3–10 GHz frequency-domain of small trees are obtained by indoor wideband polarimetric measurement system.
The results show that morphological characteristics of vegetation at different frequencies can be obtained by the differential propagation constant of polarized electromagnetic wave.
At low frequencies, the plants with structural features presented oriented distribution.
However, the plants show random distribution of the echoes at higher frequencies, which is mainly from the canopy.
The research provides important information to choose the coherence models employed in the parameters retrieval of vegetations.
