Abstract
A method and apparatus for simulating a lofargram in a multipath sonar sym 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 eigenrays with terms corresponding to at least one of the simulated sonar parameters. A lofargram means is joined to the defining means for interpolating said eigenrays to produce simulated lofargram output signals. The invention can also incorporate a report means for generating a report from the simulated lofargram output signals.
