摘要
We estimate geoacoustic parameters of a layered bottom in a shallow waveguide, which is nonuniform along the path, using the data of the full-scale experiment and the matched-field method. On the basis of the available a priori geological and geophysical data, a waveguide consisting of two sedimentary layers and the underlying half-space is used as the reference geoacoustic model. When seeking the geoacoustic parameters corresponding to the global minimum of the objective function, the hybrid algorithm, which is a combination of the fast simulated annealing method and the Hook-Jeeves method of direct search, is used.
