Shallow water reverberation modeling using an autoregressive range-scattering function approach

Abstract

The primary limitation on system performance for active sonars is reverberation - the reradiation of acoustic energy back to the receiver from inhomogeneities in the physical properties of the medium and its boundaries. A new technique for modeling reverberation using an autoregressive power spectral density function to describe the range-scattering function of the reverberation channel is presented. The method is used to estimate the range-scattering function from sampled reverberation time-series.
