В настоящее время волномерные буи (ВБ) повсеместно применяются для измерения статистических и спектральных параметров волн. Современные методы определения пространственного спектра волн используют их представление рядом Фурье, коэффициенты которого определяются по измерениям волновых процессов. Конструктивное исполнение современных ВБ позволяет измерять ординаты волн и углы волнового склона, чего достаточно для определения пяти членов ряда Фурье. Однако по измерениям волновой поверхности можно определить до девяти членов ряда. Для определения недостающих четырех членов необходима информация о кривизне волн. Отсутствие этой информации приводит к низкой разрешающей способности метода и к наличию в спектре отрицательных областей.</p></sec><sec><title>Цель работы</title><p>Цель работы.

Приведены теоретические обоснования предложенного метода, представлено математическое моделирование нерегулярных волновых процессов в широком диапазоне интенсивности волн и экспериментальное исследование трех спектров волнения с троекратным повтором каждого из них.</p></sec><sec><title>Результаты</title><p>Результаты. Разработан метод определения кривизны волн по измерениям ВБ традиционной формы посредством численного дифференцирования результатов измерений углов волнового склона с использованием информации о скорости распространения волн. Метод дополнен корректировкой амплитудных значений по критерию соответствия спектральных характеристик волновых процессов. Моделирование показало хорошее совпадение расчетной кривизны с заданными значениями. Отклонение по дисперсии составило менее 1 %. Экспериментальное исследование показало большее отклонение по дисперсии – до 9 %, что можно объяснить инструментальной погрешностью и неучтенным влиянием отраженных волн.</p></sec><sec><title>Заключение</title><p>Заключение. Отличительной особенностью метода является использование измерений ординат волн и углов волнового склона, выполненных ВБ традиционной формы без дополнительных конструктивных элементов. Необходимы дополнительные исследования метода для определения влияния других факторов волнения (крутизны волн, ширины спектра, трехмерной структуры волны и т. д.) на результаты определения кривизны и пространственного спектра.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Modern wave buoys due to their design make it possible to determine a directional wave spectrum using five coefficients of the Fourier series. However, up to nine members of the series can be determined from wave surface measurements. To determine the missing four members, information about wave curvature is necessary. It cannot be obtained by direct measurements with wave buoys of a conventional shape - a sphere, a cylinder or a saucer. The lack of information about the curvature of waves when determining the directional spectrum leads to its low resolution and to the presence of negative regions.</p></sec><sec><title>Aim</title><p>Aim. To develop a method for determining the curvature of waves from measurements with conventional shape wave buoys.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Theoretical substantiations of the proposed method were presented, as well as mathematical modeling of irregular wave processes in a wide range of wave intensities and an experimental study of three wave spectra with a threefold repetition of each of them.</p></sec><sec><title>Results</title><p>Results. Numerical simulations demonstrated a good agreement between the calculated curvature and the set values. The variance deviation was less than 1%. The experimental study demonstrated a greater deviation in variance - up to 9%, which can be explained by the influence of an instrumental error and by an unaccounted influence of reflected waves.</p></sec><sec><title>Conclusion</title><p>Conclusion. On the basis of the study, the method for determining the curvature of waves by numerical differentiation of wave slope measurements using information on a wave propagation speed has been developed. The method was supplemented by correcting amplitude values according to the criterion of matching the spectral characteristics of wave processes. Additional studies of the developed method are required to determine the influence of wave factors such as wave steepness, spectrum width, random multidirectional waves, etc. on the calculated curvature and on the directional spectrum.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>волномерный буй</kwd><kwd>пространственный спектр</kwd><kwd>кривизна волн</kwd><kwd>скорость волн</kwd><kwd>численное дифференцирование</kwd><kwd>преобразование Фурье</kwd></kwd-group><kwd-group xml:lang="en"><kwd>wave buoy</kwd><kwd>directional spectrum</kwd><kwd>wave curvature</kwd><kwd>wave speed</kwd><kwd>numerical differentiation</kwd><kwd>Fourier transform</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Инициативная работа.
