Abstract

Even at usual meteorological conditions appear fluctuations of amplitude and phase of millimeter (MM) and SubMM radiowaves during their propagation through the atmosphere thickness over the terrestrial covers with rough irregularities [1]. Within a distance of several kilometres with the heights of corresponding points of 10...15 m the coherent component of MMW being reflected from a terrestrial surface, and added up to one propagating through free space (in presence of turbulence) creates a field interference structure with short-term fade-out [2]. The maximal proficiency of digital telecommunication and data transferring systems is obtainable under such conditions by matching of amplitude and phase spectra of signal and frequency response of the propagation medium as an atmospheric radiochannel [1]. Hence, Frequency Response Functions (FRF) and Scattering Incatrices (SI) [3] could be of the most interest describing characteristics of MM/SMM Wave at the receiving point.
