Abstract

Способ для применения в морской сейсмической съемке, предусматривающий буксирование по меньшей мере части расстановки морской сейсмической съемки; передачу составного сейсмического свип-сигнала от расстановки морской сейсмической съемки, причем составной сейсмический свип-сигнал предусматривает некоторое количество рандомизированных отдельных сигналов, которые имеют разные частоты относительно друг друга, и их испускают одновременно; и получение соответствующей возвратной волны для каждого отдельного свипа.
