Experimental investigation of side wave formation in forest covers

Experiments on propagation of very-high-frequency and ultrahigh-frequency waves over short distances between antennas immersed in the forest environment with different structure and species composition are discussed. It is shown that the biometric parameters of the forest vegetation and the radiation frequency play a decisive role in the formation of side walls propagation along the top layer of the forest. It is found that the conventional approach to describing the attenuation property of the forest environment using the notion of the attenuation per unit length is incorrect in the presence of side walls.
