Polarization of radiation of an aperture random antenna

Бесплатный доступ

The polarization characteristics of radiation of an aperture random antenna are investigated by using the triad cluster method of simulation. The limitations inherent in the traditional definitions of radio waves polarization are shown and the method applicable to the study of the the triad -cluster method of simulation -model of aperture random antenna is selected. 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 the triad cluster method of simulation -model, which characterize the stochastic polarization of radiation of a typical three element aperture random antenna, are presented. The factors affecting the properties of stochastic polarization are considered (radiation frequency, amplitude and phase errors, correlation of errors in aperture random antenna). It is shown that the main factor is the unpredictable nature of the aperture random antenna mode of operation, which is taken into account in the the triadcluster method of simulation 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.
