Получены формулы для расчета статистически среднего значения и коэффициента вариации энергии сигнала упругого обратного рассеяния, приходящего из приповерхностного слоя воды со случайно-неоднородными показателями поглощения и рассеяния. Приведены примеры зависимости указанных характеристик сигнала от коэффициентов вариации оптических характеристик воды. Установлено, что флуктуации показателя поглощения приводят к увеличению средней энергии принимаемого сигнала, а флуктуации показателя рассеяния — к ее небольшому уменьшению. Значительное уменьшение средней энергии эхо-сигнала может наблюдаться при взаимно коррелированных флуктуациях показателей поглощения и рассеяния, т. е. в случае, когда флуктуирует показатель ослабления при неизменном альбедо однократного рассеяния. Высказаны соображения о том, каким образом могут быть построены алгоритмы оценки средних значений оптических характеристик воды и параметров их неоднородностей по среднему значению и коэффициенту вариации энергии эхо-сигнала. </p></abstract><trans-abstract xml:lang="en"><p>Theoretical models of the statistical characteristics of the lidar echo signal have been developed to interpret the results of optical sounding of heavily eutrophicated water bodies. Formulas are obtained for calculating the statistically average value and coefficient of variation of the energy of the elastic backscattering signal coming from the near-surface layer of water with randomly inhomogeneous absorption and scattering coefficients. Examples of the dependence of the indicated signal characteristics on the coefficients of variation of the optical characteristics of water are given. It has been established that fluctuations in the absorption coefficient lead to an increase in the average energy of the received signal, and fluctuations in the scattering coefficient to its slight decrease. A significant decrease in the average echo signal energy can be observed with cross-correlated fluctuations in the absorption and scattering coefficients, i. e. in the case when the attenuation coefficient fluctuates at a constant single scattering albedo. Considerations are made on how algorithms for estimating the average values of the optical characteristics of water and the parameters of their inhomogeneities from the average value and the coefficient of variation of the echo signal energy can be constructed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лидар</kwd><kwd>вода</kwd><kwd>упругое рассеяние света</kwd><kwd>флуктуации гидрооптических характеристик</kwd><kwd>статистические свойства лидарных эхо-сигналов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lidar</kwd><kwd>water</kwd><kwd>elastic light scattering</kwd><kwd>fluctuations in hydrooptical characteristics</kwd><kwd>statistical properties of lidar echoes</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках реализации Программы стратегического академического лидерства «Приоритет 2030» ННГУ (№ темы Н-468–99_2021–2023) и по государственному заданию (тема № 0030–2021–0006).</funding-statement><funding-statement xml:lang="en">The work was carried out as part of the implementation of the Strategic Academic Leadership Program “Priority 2030” of UNN (direction № N-468-99_2021–2023) and according to the State assignment (theme № 0030-2021–0006).</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">Долин Л.С., Савельев В.А.
