Estimating the acoustic parameters of a model of a shallow-water seafloor using a priori geological and geophysical information and the Wigner transform

Abstract

The results of estimating the acoustic parameters of a laminated bottom in a shallow-water region, which are averaged along the propagation path, are presented. The results of experiments on the propagation of low-frequency acoustic pulses in a water layer served as the initial information for obtaining estimates. The Wigner transform and a priori geological and geophysical information were used to estimate the parameters of normal waves and acoustic characteristics of the seafloor.
