Sonar Simulator?

[andwii]

well because I can't think of a better area that people could answer me with I put it in the SH3 thread (sorry I know its out of place)

Anyway I was wondering if anyone had or knew how to get a waterfall display sonar simulator (as in software not hardware). I know Janes 688i had one in the game, but I was looking for one with the most realistic set up to play around with to get a better understanding of how the waterfall sonar works. Thanks

A lot of multi-mode ham radio software use a waterfall display. It's an actual application that you can see how a waterfall display works. PSK31 software usually has it.
