Simulation of polarization characteristics of aperture random antenna radiation

The polarization characteristics of radiation of an aperture random antenna (ARA) are investigated by using the triad-cluster method (TCM) of simulation. The histograms of distribution of azimuthal and meridional angular coordinates of the electric E-field and magnetic H-field strengths, found experimentally in real conditions, are presented. The similar histograms obtained by using the TCMmodel, which characterize the stochastic polarization of radiation of a typical three-element ARA, are presented.

The factors affecting the properties of stochastic polarization are considered (radiation frequency, amplitude and phase errors, correlation of errors in ARA). It is shown that the main factor is the unpredictable nature of the ARA mode of operation, which is taken into account in the TCM framework and realized by probabilistic combinatorics of components of the E-field and H-field vectors. The obtained data demonstrate both the practical effectiveness of the proposed methods and means for the study of radio waves stochastic polarization, as well as its specific properties. The obtained data can be in the simulation of confidential information leakage channels, as well as in other applied problems of the random antenna theory.
