Abstract
In this study, range-frequency interference is analyzed in the propagation of acoustic waves in shallow-water waveguides. The interference pattern is examined using image processing techniques to produce the waveguide-invariant parameter beta. The variability of the beta-distributions of four geoacoustic parameters in a sediment layer and four typical sediment types is characterized by skewness and kurtosis. The result shows that a low value of skewness and a high value of kurtosis appear in the hard-sediment case and a high value of skewness and a low value of kurtosis appear in the soft-sediment case. This analysis technique will be useful in geoacoustic parameter inversion. (C) 2010 The Japan Society of Applied Physics
