Abstract :
This paper presents a comparison between a wave propagation model based on the parabolic wave equation (PE) technique and a model based on the geometric theory of diffraction (GTD) technique, for calculating the propagation attenuation in a forest environment. To compare the PE model and the GTD model, we have made the comparisons against measurements in a fir forest environment.
