STEPWISE RECONSTRUCTION OF THE CHARACTERISTICS OF A LAYERED ELASTIC BOTTOM FROM THE REFLECTION COEFFICIENT

The relation between the sound reflection coefficients measured at the sea bottom at fixed grazing angles and a fixed frequency and the char acteristics of the sediment layer and the underlying halfspace is cons idered. Based on this relation, a method of the reconstruction of the sea bottom characteristics is developed for a bottom model in the form of a sediment layer overlying an elastic halfspace. Using this model, the reconstruction of the characteristics of a layered elastic bottom is performed from the experimental dependences of sound reflection lo ss.
