Analysis on phase information of polarized radar in moni - toring vegetation

摘要

T-matrix method was employed to analyze the relation between the co - polarization phase difference of back scattering of vegetation and its geometrical and physical parameters, and the effect from the frequency and the inci- dent angle of radar based on this kind of relation. The results showed that the phase difference is affected by the geomet - rical parameters (such as the shape, the growth state of wat - tle and leafage etc.) and the physical parameters (such as the real part and the imaginary part of the dielectric constant etc.) in different ways.
