Abstract

Система и способ для исследования области недр, которая содержит интересующий участок объекта, содержащие обеспечение данных о частотной характеристике для интересующего участка объекта и сейсмического источника. Сейсмический источник управляется, чтобы обеспечить сейсмические волны в полосе частот, выбранной на основе данных о частотной характеристике. Сейсмический источник затем активируется, чтобы ввести сейсмические волны в участок недр. Отражения сейсмических волн регистрируются в сейсмическом приемнике.
