Comparing Kirchhoff-approximation and boundary-element models for computing gadoid target strengths
(Journal article; Peer reviewed, 2002)To establish the validity of the boundary-element method (BEM) for modeling scattering by swimbladder-bearing fish, the BEM is exercised in several ways. In a computation of backscattering by a 50-mm-diam spherical void ... -
The fish swimbladder as an acoustic waveguide

Importance of the swimbladder in acoustic scattering by fish: A comparison of gadoid and mackerel target strengths
(Journal article; Peer reviewed, 1980)Previous determinations of the swimbladder contribution to the fish backscattering cross section have been hindered by ignorance of the acoustic boundary conditions at the swimbladder wall. The present study circumvents ... -
Rather-high-frequency sound scattering by swimbladdered fish
(Journal article; Peer reviewed, 1985)A new model describes acoustic scattering by swimbladdered fish of lengths from at least 8 to 36 wavelengths. It represents a fish by an ideal pressure-release surface having the exact size and shape as the swimbladder. ... -
