В статье рассматривается влияние затенения волн, находящихся вдали от наблюдателя, более близкими. Рассмотрено и выполнено имитационное моделирование морской поверхности на основе вероятностной модели Лонге-Хиггинса для состояний морской поверхности от умеренного до сильного. Для полученных моделей проведен статистический анализ видимости участков поверхности. Показано, что в рамках применяемой модели волнения, эффект затенения имеет наибольшее влияние при зондировании вдоль направления ветра, а наименьший – в направлении, ему перпендикулярном. Установлено, что при сильном волнении эффект от затенения выражен в большей степени. По результатам анализа предложен подход к учету эффекта затенения при моделировании ЭПР морской поверхности.</p></abstract><trans-abstract xml:lang="en"><p>The effectiveness of the implementation of radar systems for water areas monitoring is inextricably linked with the creation of adequate models of the radar cross-section (RCS) of the sea surface, which are required for the efficient detection and tracking of surface objects in order to ensure the safety of marine navigation. The article considers the influence of shading of waves that are far from the observer by closer ones. The modeling of the sea surface based on the Longuet-Higgins probability model for various sea surface conditions ranging from moderate to strong is considered and corresponding simulations are performed. For the obtained models, statistical analysis of the visibility of water surface areas was carried out. It is shown that within the applied wave model, the shading effect appears the most pronounced when the direction of observation is collinear with the wind direction, and the least pronounced at the perpendicular direction. It has been established that with strong waves, the effect of shading is more pronounced. Based on the results of the analysis, an approach to take into account the shading effect in modeling the RCS of the sea surface was proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ветровое волнение</kwd><kwd>эффективная поверхность рассеяния</kwd><kwd>видимость</kwd><kwd>математическое моделирование</kwd><kwd>гармонический синтез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>wind waves</kwd><kwd>radar cross-section</kwd><kwd>visibility index</kwd><kwd>numerical modeling</kwd><kwd>harmonic synthesis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания по теме  Министерства науки и высшего образования № FSEE-2020-0002.</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">Masuko H., Okamoto K., Shimada M., Niwa S.
