要約

Formulae for mean field characteristics of a circular aperture antenna focused at the Fresnel zone in the presence of phase fluctuations in the aperture are obtained. Plots that show the dependence of these characteristics on parameters of phase fluctuations (their variances and correlation radii) and location of the focusing and observation points are given. The obtained results are also suitable when studying mean characteristics of "usual" circular aperture antennas, (i.e., focused at infinity), in their Fresnel and far zones. Significant attention is paid to a comparison of results for a circular aperture antenna with similar results obtained for a linear antenna and a square aperture antenna.
