Summary:Bistatic scattering coefficients are computed for a site on a tree covered mountainside at L Band. The layer which consists of inclined trees is modeled by discrete scatterers consisting of trunks, branches, needles and leaves with varying orientations and dimensions. Due to the sloped nature of the terrain, azimuthal asymmetry occurs and this causes mixing of polarizations of the incident and scattered waves. The mean equation is solved to acquire the propagation constants inside the layer. Direct (volume) scattering is found to be the dominant scattering mechanism for the modeled layer at L band. Ground truth measurement data is used to simulate the attenuations. Further study shall be done to compare the bistatic scattering results with the ground truth measurements to be made in July 2021.
