Abstract

Сейсмические данные получают преобразованием в спектральную область данных для каждого возбуждения сейсмического источника в морской косе и для каждой частоты. Преобразованные сейсмоданные итерационно обрабатывают по схеме с сопряженными градиентами, использующей физически обоснованный предобуславливатель, для получения методом наименьших квадратов решения нормальной системы уравнений, составленной для системы уравнений очистки. Это решение обратно преобразуют в пространственно-временную область для получения очищенных сейсмоданных.
