Abstract

A modification of the numerical technique for calculating the field and delay of the signal reflected by a flat reflector and based on the Fresnel–Kirchhoff equation of the diffraction scalar field has been proposed. The relationships taking into account the size of antennas and reflector as well as changes of the amplitude and phase characteristics of repeater channels were obtained. It was shown that the signal delay characteristics in the Fresnel zone depended on the size of reflector shifting with the signal delay variations.
