I'm not really sure about what the best way to learn about the sonar model and the acoustics engine would be.
Amizaur and I have simply been playing around with the database enough to have a good feel for it, but actually there is considerable disagreement in the modding community about what is actually going on "under the hood" and what the database values mean.
This is all very much a work in progress from the standpoint of trying to get a working knowledge-base, and the culture of secrecy inhereted from SC, although thawing slightly in DW, doesn't help much.
My best suggestion is to create various test scenarios and start messing with database values and see how object behavior changes in game. The easiest way to do this is with torpedos or playable sonar sensors.
