Abstract

Раскрыт способ выполнения сейсмического свип-сигнала, включающий формирование профиля результирующей силы, создание целевого свип-сигнала сейсмической частоты с использованием профиля результирующей силы и управление сейсмическим источником с использованием созданного сейсмического свип-сигнала целевой частоты.
