- Hi,
-
- I've been told, by those who ought to know, that you can take 3 or
- more sonar transponders, send out a pulse, and then watch what happens to
- all three of them on the return trip to get an entire effective 360 deg.
- sweep of whatever you're looking at. Supposedly almost as good as having
- one rotating transponder, but no more need to rotate -- neat.
-
- So... could someone give me a reference to where I could read all
- the details about how this is done? Or, if it ought to be glaringly
- obvious and simple, explain how it's done?
-
- Thanks.
