Abstract :
Diffraction over an earth is evaluated using several methods. An enhanced analysis of propagation over irregular terrain, which offers more reliable numerical simulations for low altitude propagation and diffraction field zone without any auxiliary procedures using physical optics approximation of vector problem, is used for comparison with Fock´s series and ITU.
