Abstract

Согласно изобретению создают прямые глубинные экстраполяционные операторы с переменными длинами оператора, зависящими от максимального угла наклона, требования к точности и волнового числа. Затем создают операторные таблицы с использованием прямых глубинных экстраполяционных операторов. В дополнительном варианте реализации изобретения глубинную миграцию выполняют с использованием прямых глубинных экстраполяционных операторов в табличной форме.
