Modeling interference fading the direct and reflected narrow beams of millimeter waves above terrestrial cover and diffraction in a zone shadow of obstacle

The theoretical models of narrow mm-waves beam diffraction and interference fading are represented. Experimental data have confirmed theoretical model of amplification narrow diffractional a beam in a zone shadow of an obstacle (half plane) taking into of the gains and the directional diagrams of transmitting and receiver antennae. Offered mathematical model of interference fading may be used for prediction of fading in the terrestrial telecommunication systems
