Title:
THE EFFECTS OF IRREGULARITY SCALE ON USABLE ANTENNA APERTURE
Corporate Author:

Abstract:
It is assumed that a wave is incident on a broadside antenna array after passing through a propagation medium containing refractive-index fluctuations having a Gaussian correlation function. The influence of the irregularities on usable array directivity and effective power gain is explored as a function of the magnitude and scale of the refractive-index fluctuations, and of the extent and position of the scattering region. The domains of Fresnel diffraction geometrical optics and Fraunhofer diffraction wave theory are distinguished, and within these domains the nature of the array performance is categorized and explored for relative parameter classes.
