Analysis and Discussion of Circularly Bound Random Antenna Array Distributions
Abstract
This report details a theoretical feasibility study to investigate the performance of circular antenna arrays. The radiation performance of circularly bound random arrays with various distributions are analyzed statistically to identify regions of deterministic, transitional, and random behavior. Isotropic radiators are preferred in this analysis in view of the fact that they provide relevant information on the fundamental beamforming behavior and can be applied to provide practical estimates and ideal limitations on the maximum peaking sidelobe located in the stochastically described 3 dB sidelobe region since this regime tends to behave non-deterministically. The mathematical process required for this analysis includes a statistical formulation of the array factor, including the mean, or expected value, and the variance. Rigorous analysis from prior works on random arrays provides the framework for this work and develops into accurate estimates of the maximum peaking sidelobe behavior in a volumetric scan region. Numerical results are included to illustrate scanning from zenith to meridian elevation angles to evaluate the theory and compare the behavior of both planar circular and volumetric spherical arrays.
