Title Input parameter and phase function measurements for modelling propagation through vegetation based on the theory of radiative energy transfer
Abstract Modelling radio wave propagation through vegetation is becoming increasingly more important. Many empirical solutions have been suggested in the past. This paper outlines the use of the theory of radiative energy transfer (RET) in a generic model for propagation through vegetation at frequencies from 1 to 60 GHz. The RET offers an analytical method to the problem. This theory requires however 4 input parameters, which need to be established experimentally. Some examples of curve fitting for this process are shown. A measurement of the angular scatter pattern, the so called 'phase function', can be utilised to determine 2 of those parameters. The most suitable method is presented of measuring this phase function is presented.
