The vector radiative transport theory is used to compute the attenuation produced by a tree canopy containing random located lossy-dielectric leaves and branches at millimeter wave frequencies. Using this approach, the forward scattering approximation is used to simplify the radiative transport equation. The forward scattering approximation is used since at millimeter frequencies, the leaves and branches...
This paper discusses the results from a series of field experiments using ground-based L-band microwave active/passive sensors. Three independent approaches are applied to the microwave data to determine vegetation opacity of coniferous trees. First, a zero-order radiative transfer model is fitted to multi-angular microwave emissivity data in a least-square sense to provide “effective” vegetation...
The radiative transport theory has been used to compute the attenuation produced by a canopy of a tree containing random located lossy-dielectric disc and branches at millimeter wave frequencies. Using this approach, the forward scattering approximation is used to simplify the solution of the radiative transport equation. The forward scattering approximation is used since at millimeter frequencies,...
