Resumo(s)
This paper presents a feasibility study on the extension of the point scatterer formulation to include time-varying effects caused by wind induced channel dynamics. This modeling approach, which is based on a ray-tracing algorithm, employs various point scatterers with specific radiation characteristics, distributed within a computational volume, to characterize the electromagnetic behavior in the presence of trees and vegetation volumes. This propagation model has now been extended to include the time-varying received signal level, caused by the swaying motion of branches, twigs and leafs. To this extent, a statistical model is used to characterize the time-varying attenuation of each multipath component. The performance of the proposed model is assessed against measurements intended
to record the dynamic re-radiation pattern of a tree in various windy conditions, which included four wind directions and two wind speeds.
