Abstract

Способ подавления помех в морских сейсмических сигналах включает введение перекрестных волн-спутников в морские сейсмические сигналы реакции на давление и морские сейсмические сигналы реакции на движение, получаемые одновременно с ними. Определяют разность между сигналами, содержащими перекрестные волны-спутники. Эту разность используют для подавления помех по меньшей мере в одном из сигналов реакции на давление и сигналов реакции на движение.
