Abstract

The paper describes a radio frequency (RF) propagation model for a forest. The forest is modelled using discrete method where incoherent waves dominate over coherent waves. Tree trunks, branches, and needles are characterised by randomly oriented, lossy dielectric cylinders. Leaves are characterised by dielectric discs. The scatterer orientation and distribution are prescribed. The biophysical input parameters to the model are gathered from an experimental site. Theoretical attenuation based upon the biophysical parameters of vegetation is compared with measured values for both horizontal and vertical polarisation and excellent agreement is obtained
