Abstract

Данное изобретение относится к способу сбора сейсмических данных из смешанного источника, который использует новый подход к определению выделения случайных моментов времени между последовательными взрывами. Выделение случайных моментов времени согласно некоторым вариантам настоящего изобретения может быть осуществлено на основе распределения равномерно распределённых чисел при τ >1(2ƒ), где τ обозначает полуширину равномерного распределения и ƒ обозначает самую низкую значимую величину частоты в массиве полученных данных.
