В статье рассмотрены теоретические и практические аспекты измерения диэлектрической проницаемости земной поверхности при ее облучении радиосигналом в двухпозиционной системе из беспилотных летательных аппаратов. Требуемая глубина проникновения зондирующего радиосигнала под поверхность достигается использованием UHF-диапазона и наклонным облучением в условиях полного (псевдополного) преломления электромагнитной волны на границе «воздух-поверхность». Новизна предлагаемого подхода заключается в наклонном облучении земной поверхности горизонтально и вертикально поляризованным радиолокационным сигналом с последующей регистрацией амплитуд и фазовых сдвигов осцилляций интерференционных волн и в нахождении угла Брюстера по параметрам интерференционной волны. Практическим применением такого подхода являются измерение влажности сельскохозяйственных почв и определение прочностных характеристик морского льда.</p></abstract><trans-abstract xml:lang="en"><p>Remote assessment of the dielectric characteristics of the earth’s surface is in demand for solving various industrial tasks. The article discusses the theoretical and practical aspects of measuring the dielectric const ant of the Earth’s surface when it is irradiated with a radio signal in a two-position system from unmanned aerial vehicles. The required depth of penetration of the probing radio signal under the surface is achieved using the UHF band and oblique irradiation under conditions of complete (pseudo-complete) refraction of the electromagnetic wave at the air-surface boundary. The novelty of the proposed approach lies in the oblique irradiation of the Earth’s surface with a horizontally and vertically polarized radar signal, followed by registration of amplitudes and phase shifts of interference wave oscillations.and finding the Brewster angle by the parameters of the interference wave. The practical application of this approach is to measure the moisture content of agricultural soils and determine the strength characteristics of sea ice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дистанционное зондирование земной поверхности</kwd><kwd>диэлектрическая проницаемость</kwd><kwd>угол Брюстера</kwd><kwd>интерференционная волна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>remote sensing of the earth’s surface</kwd><kwd>dielectric permittivity</kwd><kwd>Brewster’s angle</kwd><kwd>interferential wave</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Коллектив авторов благодарит Агрохолдинг «Степь» (Российская Федерация) за предоставленные для исследования опытные поля.</funding-statement><funding-statement xml:lang="en">The team of authors thanks Agroholding “Steppe” (Russian Federation) for the experimental fields provided for the study.</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">How-Wei, C.
