Abstract

The authors present a mathematical description and work out a numerical analysis of the frequency response functions of the turbulent atmospheric radiochannel in the millimeter-wave band, taking into account the impact of the roughness of underlying terrestrial surfaces. It was theoretically shown and experimentally confirmed at /spl lambda/=2.2 mm that underlying angles over the terrestrial surface exceeding 6/spl deg/, an interference structure becomes disrupted, and the radiochannel transmission band closely corresponds to millimeter-wave of free space. Within a distance of several km with heights of corresponding points of 10-15 m, an interference structure of millimeter-wave field is retained. The radiochannel transmission band encompasses 1000 MHz and tends to broaden when the transmitter antenna height is scaled down.<>
