Abstract
Расчетный сигнал датчика вертикальной скорости определяют по записанному сигналу датчика давления. Построенный сигнал датчика вертикальной скорости определяется как линейная комбинация расчетного сигнала датчика вертикальной скорости и записанного сигнала датчика вертикальной скорости в данных сейсмической косы с двумя типами датчиков с использованием коэффициента смеси в качестве константы пропорциональности. Восходящая компонента волнового поля давления определяется как половина от разности записанного сигнала датчика давления и построенного сигнала датчика вертикальной скорости в качестве функции коэффициента смеси. Ошибка в восходящей компоненте волнового поля давления определяется путем распространения (накопления) ошибок в членах, представляющих записанный сигнал датчика давления и построенный сигнал датчика вертикальной скорости. Определяется значение коэффициента смеси, которое минимизирует ошибку в восходящей компоненте волнового поля давления.
