Abstract

Способ оценки набора физических параметров, включающий в себя итеративное инвертирование уравнения с целью минимизации погрешности между данными моделирования и измеренными данными и обеспечения оцениваемого набора физических параметров, причем указанное итеративное инвертирование содержит по меньшей мере первый шаг инверсии и второй шаг инверсии, и при этом данные моделирования зависят от вектора модели, представляющего набор физических параметров, применение оператора сжатия к вектору модели, представляющему набор физических параметров, для уменьшения числа свободных переменных и получения сжатого вектора модели и изменение оператора сжатия между первым шагом инверсии и вторым шагом инверсии.
