Аннотация
В работе рассматривается численная реализация метода обращения полного волнового поля на основе асимптотического решения уравнения Гельмгольца. Классическая постановка задачи заключается в поиске минимума штрафной функции, характеризующей среднеквадратичное уклонение модельных данных от зарегистрированных при проведении полевых работ. Для минимизации целевого функционала обычно применяются методы локальной оптимизации, такие как метод сопряженных градиентов. Именно вычисление градиента штрафной функции и является самой ресурсоемкой частью задачи. Асимптотический подход к решению обратной динамической задачи сейсмики заключается в замене дорогостоящей конечно-разностной процедуры расчета функции Грина краевой задачи частотно-зависимым лучевым трассированием. Функции Грина рассчитываются на основании данных о времени пробега вдоль лучей, об амплитуде и о геометрическом расхождении. Серия численных экспериментов для широкоизвестной модели Marmousi демонстрирует эффективность применения такого подхода к реконструкции макроскоростного строения сложноустроенных сред для низких временных частот. При сопоставимом качестве решения обратной задачи применительно к стандартному конечно-разностному подходу скорость расчетов асимптотического метода на порядок выше.
