Field Statistics of the Circular Aperture Antennas
The field statistics of the circular aperture antennas focused to the Fresnel zone with the presence of the phase fluctuations on its aperture is considered. The basic relationships are formulated in the form being invariant with respect to the focus point location. This allows using them when study...

| description | The field statistics of the circular aperture antennas focused to the Fresnel zone with the presence of the phase fluctuations on its aperture is considered. The basic relationships are formulated in the form being invariant with respect to the focus point location. This allows using them when studying both focused and unfocused (ordinary) antennas in their Fresnel and far zones. The formulas for mean and fluctuation characteristics of the field are given, the plots illustrating these characteristics versus the fluctuations dispersion and correlation radius presented. The results obtained for the circular aperture are compared with those analogous obtained earlier by the authors for the linear antenna. |

The field statistics of the circular aperture antennas focused to the Fresnel zone with the presence of the phase fluctuations on its aperture is considered. The basic relationships are formulated in the form being invariant with respect to the focus point location. This allows using them when studying both focused and unfocused (ordinary) antennas in their Fresnel and far zones. The formulas for mean and fluctuation characteristics of the field are given, the plots illustrating these characteristics versus the fluctuations dispersion and correlation radius presented. The results obtained for the circular aperture are compared with those analogous obtained earlier by the authors for the linear antenna. Рассмотрена статистика поля антенны с круглой апертурой, сфокусированной в зону Френеля, при наличии в ее апертуре фазовых флуктуаций. Основные соотношения сформулированы в виде, инвариантном относительно расположения точки фокуса (фокусировки). Это позволяет использовать их при изучении поля как сфокусированных, так и несфокусированных (“обычных”) антенн в их зоне Френеля и в дальней зоне. Приведены формулы для средних и флуктуационных характеристик поля и графики, иллюстрирующие зависимость этих характеристик от дисперсии и радиуса корреляции флуктуаций. Результаты, полученные для круглой апертуры, сопоставлены с результатами, ранее полученными авторами для линейной антенны.
