Основное внимание уделяется учету реальной геометрии отражателя, восстановленной на основе высокоточных лазерных измерений. На основе полученных данных был разработан новый двухдиапазонный коаксиальный облучатель, который обеспечивает совмещение фазовых центров в S- и X-диапазонах, а также высокую изоляцию между портами. Оптимизация конструкции и прогнозирование характеристик антенны были выполнены с использованием электродинамического моделирования в среде Ansys HFSS с учетом действительного профиля параболы. Изготовленный прототип прошел лабораторные испытания, которые подтвердили расчетные прогнозы. Ширина луча составила около 0,7о , апертурная эффективность достигла 56 %, а отношение усиления к температуре шума G/T – порядка 25,9 дБ/К, что соответствует требованиям радиолинии для приема сигналов низкоорбитальных спутников. Результаты демонстрируют, что точный учет формы отражателя и корректная настройка облучателя позволяют достичь требуемых характеристик антенны без замены параболического зеркала. Тем самым подтверждается возможность эффективной модернизации существующих наземных антенн среднего класса за счет интеграции методов высокоточной геометрической реконструкции и электродинамического моделирования.</p></abstract><trans-abstract xml:lang="en"><p>This paper discusses the modernization of a ground station antenna with a parabolic reflector of 3.7 m diameter for operation in the S- and X-bands. The main focus is on accounting for the actual reflector geometry, which was reconstructed based on high-precision laser measurements. Using the obtained data, a new dual-band coaxial feed was developed, ensuring the alignment of phase centers in the S- and X-bands and high port isolation. The antenna design optimization and performance prediction were carried out using electromagnetic modeling in Ansys HFSS, taking into account the actual parabolic profile. The fabricated prototype underwent laboratory testing, which confirmed the simulation results. The beamwidth was approximately 0.7o , the aperture efficiency reached 56%, and the gain-to-noise temperature ratio (G/T) was about 25.9 dB/K, meeting the requirements of the radio link for receiving signals from low-orbit satellites. The results demonstrate that accurate consideration of the reflector shape and proper feed tuning make it possible to achieve the desired antenna characteristics without replacing the parabolic mirror. Thus, the feasibility of efficient modernization of existing medium-class ground antennas through the integration of high-precision geometric reconstruction methods and electrodynamic modeling is confirmed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>параболическая антенна</kwd><kwd>наземная станция</kwd><kwd>S диапазон</kwd><kwd>X диапазон</kwd><kwd>коаксиальный облучатель</kwd><kwd>низкоорбитальный спутник</kwd><kwd>дистанционное зондирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>parabolic antenna</kwd><kwd>ground station</kwd><kwd>S-band</kwd><kwd>X-band</kwd><kwd>coaxial feed</kwd><kwd>low-orbit satellite</kwd><kwd>remote sensing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование финансировалось Комитетом науки Министерства науки и высшего образования Республики Казахстан (BR27198365 «Разработка оптикоэлектронной системы в коротковолновой инфракрасной области спектра в контексте развития космических систем ДЗЗ Казахстана»).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Casco N.A.
