Abstract

Система сейсмоприемной косы для измерения вторичного электромагнитного поля подповерхностных слоев включает сейсмоприемную косу, располагающуюся на дне акватории. Сейсмоприемная коса содержит группу электромагнитных датчиков, расположенных на определенном удалении друг от друга. Блок управления системой находится в связи с датчиками, включает приемопередатчик для обмена сигналами с соответствующими датчиками. Блок управления системой содержит приемник сигнала глобальной навигационной системы. Блок управления системой включает процессор, выполненный с возможностью получения сигналов, принимаемых сенсорными элементами в соответствующей системе сейсмоприемной косы. Процессор выполнен с возможностью обработки сигналов, полученных в результате комбинирования и разновременного суммирования, от различных сенсорных элементов сейсмоприемной косы и сенсорных элементов в соответствующей системе. Процессор выполнен с возможностью статистической оценки сигналов, полученных в результате комбинирования и разновременного суммирования. Блок управления системой расположен в сплавном устройстве.
