Paper Abstract

A general model that describes beam wave propagation through a dispersing and absorbing, clear, turbulent, heterogeneous atmosphere is extended and related to common experimental quantities, viz, intensity covariances, angle-of-arrival, and the mutual coherence function. These experimental quantities are assumed to be measured via parabolic reflector antennas; aperture averaging is taken into account. Explicit expressions for the second and fourth order coherence functions for a general beam wave are derived; it is found that log-amplitude! Phase correlations play an important part in the derivation of these two auantities. A brief review of reflector antenna theory is given. Three experimental situations are considered: the quasi-optical method; intensity covariance via two reflector antennas; the long base-line interferometric method.
