Estimation of sea bottom parameters from the angle-frequency resonances of the reflection coefficient

The resonance structure of the frequency response is used for the determination of sea bottom properties. The behavior of the resonance characteristics is investigated in the plane of two different bottom parameters for a fixed angle of incidence. The features of the behavior of the resonance structure characteristics are used to develop the procedure for evaluating the parameters of a layered sea bottom. With the proposed procedure, the parameters of a layered sea bottom are determined from model data in which an error is artificially introduced. The efficiency of the bottom parameter determination is shown to increase when several characteristics of the resonance structure are used simultaneously.
