В ходе эксперимента была проведена детальная регистрация гидродинамики водных слоев с помощью разработанной системы океанографических сенсоров (CTD). Данная система позволила выполнить океанографические съемки интенсивных внутренних волн с высоким разрешением, используя как заякоренные, так и буксируемые сенсоры. Акустическая составляющая эксперимента SWARM-95 проводилась с использованием двух стационарных акустических трасс, ориентированных под разными углами к фронту интенсивных внутренних волн. Интенсивные внутренние волны в эксперименте приводили к значительным акустическим эффектам, обусловленным рефракцией модовых лучей в горизонтальной плоскости и взаимодействием вертикальных мод. В работе показано, что в результате голографической обработки интерференционной структуры поля в точке приема формируются две отдельные группы спектральных пятен. Первый набор спектральных пятен соответствует звуковому полю в невозмущенном волноводе. Второй набор спектральных пятен соответствует гидродинамическому возмущению звукового поля интенсивными внутренними волнами. Данный эффект наблюдается для обеих акустических трасс эксперимента. Показано, что интерференционная структура звукового поля в невозмущенном волноводе и его гидродинамическое возмущение восстанавливаются отдельно путем фильтрации спектральных пятен в области голограммы. В работе продемонстрированно восстановление передаточной функция невозмущенного волновода и временная изменчивость гидродинамики океанской среды.</p></abstract><trans-abstract xml:lang="en"><p>The results of data interferometric processing of the oceanographic large-scale experiment SWARM-95 on the coast of New Jersey are submitted in the paper. During the experiment, numerous sensors were deployed for registrations of hydrodynamics of water layers. They performed high-resolution oceanographic surveys of intensive internal waves by using conductivity–temperature–depth (CTD) casts and tows sensors. The acoustic component of experiment SWARM-95 is carried out on two stationary acoustic tracks at presence of intensive internal waves. The intensive internal waves led to significant 3D acoustic effects: horizontal refraction of modes and modes coupling. Within framework of experimental data processing the interference pattern of source sound field in receiver is analyzed by holographic processing. In result of holographic processing of interference pattern the two separated sets of spectral spots are obtained. The first set of spectral spots corresponds to sound field in unperturbed waveguide. The second set of spectral spots corresponds to hydrodynamic perturbation of sound field by IIW. The interference patterns of sound field in unperturbed waveguide and its hydrodynamic perturbation are recovered separately by filtering of one set of spectral spots in hologram domain. The transmission function of the unperturbed waveguide and the temporal variability of the ocean environment are restored.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гидродинамика</kwd><kwd>океанический шельф</kwd><kwd>внутренние волны</kwd><kwd>звуковое поле</kwd><kwd>интерферограмма</kwd><kwd>голограмма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrodynamics</kwd><kwd>oceanic shelf</kwd><kwd>internal waves</kwd><kwd>sound field</kwd><kwd>interferogram</kwd><kwd>hologram</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research was supported by grants of RFBR (№ 19–29–06075 and № 19–38–90326).</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">Чупров С.Д.
