I am looking to build a wide underwater wing to mount two hydrophones, preferably at each end of the wing. The idea is to use this, along with other hydrophones to detect and localise cetaceans. The design must be as stable as possible and can't vary a huge amount with tow speed.
I've sketched two basic designs but have no experience in building such things.
Side scan sonar must have to be pretty stable, however none of the wing system seem wide enough for the purposes of this array.
What do people think?
Cheers
Jamie
