Azimuth angle errors as affected Fresnel diffraction on the large obstacles

Abstract

The errors of measuring of the transmitter azimuth in of Fresnel diffraction approach are calculated. They are created by influence of the large opaque screen with straight or by an uneven border. They is analysed as a function of the transmitter height for the various of the selvedge inclination, she turn and of the amplitudes of sinusoidal roughness of the boundary. Calculations at a straight border are executed in approaching of geometrical theory of diffraction. At a rough border by the method of numeral integration in Kirchhoff approaching.
