Acoustic Flank Array Power Requirements

[a***@a.com]

Folks

I'm looking for a first order approximation for the power requirements
of a nominal passive flank array.

Given that all I want to do is collect acoustic data within a certain
band and record it for offboard processeing, and my vehicle can support
N hydrophones in a planar array, is there a rule of thumb for power
requirements?

My research suggests that scaling at a rate of 1 Watt per hydrophone is
not unreasonable. Any thought or suggestions?

Thanks!

That seems a little high, a towed seismic streamer with 6000 hydrophones
only uses a 20 Amp power supply (I think at 200 V). That has to power the
GPS and run the comms circuit as well as the first stage of the signal
processing.

But, as you say, right to within an order of magnitude.
