Abstract :
A simplified ray-optics (scalar) theory is presented which can be used to calculate interference patterns in the shadow of a diffracting obstacle whose transverse profile consists of two or more straight line segments. The theory is applicable when the pathlength-to-wavelength ratio is large and the diffraction angle is small, conditions typical of terrestrial microwave diffraction links over conical mountain peaks. Scale-model test results show that the theory quite accurately predicts the pattern structure.
