Anyways... I didn't know it was done IRL  , but it does make sense of course... it should screw ASDIC to hell! |
Actually, on a soft bottom sea floor (sand, mud), I'd expect that a large metal object, like a submarine, would return a sharp, focused and easily recognized active SONAR/ASDIC echo. I'd think you'd stand out from the bottom like a sign post. Wrecks certainly do.
Passive hydrophone's might not find you, but active sure should. |
I've read a couple of times that the closest you are to the bottom, the more complicated it is to pick up a return... mmmh..:hmm: |
Every time this topic comes up, someone goes with what they think makes sense. Not meaning to pick on you, Seafarer, but the reality was far different. At Lingayen Gulf S-38 was grounded on three separate ocassions, and every time it worked. At one point her captain, 'Moon' Chapple, parked on a steep slope and slid down, only to take her up and do it over again! If I remember from Roscoe not only did the sand absorb the sonar waves, but also the shock waves from the depth charges.
