Re: [PSUBS-MAILIST] passive hydrophone array pictures!

[Jon Wallace <jonw@psubs.org>]

David,

Thanks for posting the photos.  I recall you saying something about the 
plastic cups as far as directionality, but I don't recall exactly what 
it was.  Assuming the plastic cups are not effective at producing 
directionality, what do you hope to come up with in terms of testing 
data?  Assuming you found a material that did effectively provide 
directionality, would it be more advantageous to have one element that 
could be rotated, rather than 18 elements that are switched 
mechanically?  Also, since part of the reason for having one of these is 
for surface collision avoidance, it would seem that a 20 degree cone 
would be a bit narrow when surfacing and a unit pointing upwards will be 
required.
