Abstract

Способ устранения влияний воздушной волны из данных морской электромагнитной разведки, включающий размещение в воде электромагнитного источника и по меньшей мере одного приемника, измерение электромагнитного отклика на первом расстоянии источник-приемник, определение масштабированной версии отклика воздушной волны на таком расстоянии источник-приемник, при котором «земляной» отклик пренебрежимо мал, и использование масштабированного отклика воздушной волны для определения «земляного» отклика, измеренного на первом расстоянии. При использовании этого способа может быть достигнута улучшенная оценка «земляного» отклика.
