A method and apparatus for simulating reverberation signals in a multipath sonar system is provided. The invention includes an input means for providing a plurality of simulated sonar system parameters. A defining means is joined to the input means to establish a plurality of eigenray parameters with terms corresponding to at least one of the simulated sonar parameters. A reverberation means is joined to the defining means for extrapolating said defined eigenray parameters responsive to the simulated sonar parameters to produce output signals simulating reverberation in the multipath sonar system.
