On Multiple Edge Diffraction and Multiple Reflections of Microwaves over Terrain

Abstract

This report describes a computer model which is an extension of the method of Deygout-Meeks for computing power density on target from microwaves propagated over terrain. The Meeks procedure is concerned with broadcast/ isotropic radiation at very high frequencies (vhf) and accounts for the effects of diffraction across a single knife edge, as well as ground reflections of microwaves over electrically interactive terrain at low incidence angles of transmission. This model is extended to described broadcast vhf radiation or beamed microwaves that are diffracted over two edges.
