A study of microwave multiple scattering effects in trees

Tree scattering problems at L band contain tree components in close proximity of each other. In this case, the multiple scattering effects between tree components become more significant. Scattering properties of a simple tree with primary branches over the ground are studied in this paper. The Method of Moments is applied to find the scattering amplitude of the tree. Results for the bistatic scattering cross sections including the multiple scattering are compared with single scattering results. They suggest that coherent multiple scattering effects in trees can be significant in certain cases.
