Method of data inversion for geoacoustic parameters of boftom using FM acoustic signals is presented Frequency spectra of received signals are taken as input data for application of Matched Field Processing (MFP) method. For estimation of boftom parameters we use the two-components model of sediment. As a result of matching we obtain relationship between two mechanisms of loss: energy absorption and volume scattering within boftom sediment.
