Abstract

1.Способ параметрического приема волн различной физической природы в морской среде, включающий формирование в среде рабочей зоны нелинейного взаимодействия и параметрического преобразования упругих волн накачки с измеряемыми информационными сигналами, отличающийся тем, что излучающую и приемную антенны измерительной системы размещают на противоположных границах контролируемого участка морской среды, формируют между ними зону нелинейного взаимодействия и параметрического преобразования упругих волн накачки с измеряемыми информационными сигналами, посредством излучения в нее низкочастотного акустического излучения, при этом волны накачки, взаимодействовавшие с измеряемыми информационными сигналами принимают, по меньшей мере, двумя пространственно разнесенными в горизонтальной плоскости ненаправленными приемниками, усиливают их в полосе от ноля до суммарной частоты волн накачки и информационных сигналов и переносят их частотно-временной масштаб в высокочастотную область, измеряют сигналы разности фаз пространственно-разнесенных приемников, проводят их узкополосный спектральный анализ и выделяют параметрические составляющие суммарной или разностной частоты, по которым с учетом параметрического и частотно-временного преобразования волн накачки восстанавливают исходные характеристики измеряемых информационных сигналов. ! 2.Способ по п.1, отличающийся тем, что контролируемую среду прозвучивают широкополосными низкочастотными акустическими сигналами с частотно-временной или фазовой модуляцией. ! 3.Способ по п.1, отличающийся тем, что волны накачки формируют акустическими сигналами с час 1.
