        <p>Разделение донных отложений на обособленные литологические типы с по­мощью сейсмоакустических методов исследований относится к классу задач распознавания в воде далеких объектов и заключается в определении геомет­рических и физико-механических характеристик донных осадков на основании выявления и измерения определяющих изменений, возникающих в эхо-сигнале в результате взаимодействия зондирующего акустического импульса с изучаемы­ми осадками ...</p>
