dc.description.abstract | Simulation of echo data can be useful for verifying echo integrators realized in computer software. A model is presented which associates
distinct stochastic processes with each of the following: bottom depth; number, depth, and orientation of fish in the beam; and background noise.
A measure of realism is preserved, perhaps, by (1) simulating echo registration with an ideal circular transducer of 8-deg beamwidth, moving forward at 10-knots speed; (2) allowing individual fish to be tracked
through the beam; and (3) using measurements on fish to describe the target strength. Attendees may form their own opinion of the success of the
simulation from examples to be shown - in colour. | en_US |
