Resolving power of antennas in an anisotropic turbulent medium
Abstract
The paper presents a comparative analysis of the resolutions of linear antennas located on the earth surface in the vertical and horizontal planes and detecting signals from spaced sources under the distorting effect of the atmosphere. The atmospheric effect is described by an anisotropic modification of Karman's model for the fluctuation spectrum of the refractive index. It is shown that, in the presence of a large anisotropy of the turbulent irregularities of the atmosphere, the contrast for vertical-antenna measurement is greater than that for horizontal-antenna measurement.
