To calculate the impulse response of a bubble cloud in a compressible medium, a methodology is developed that incorporates multiple scattering effects between bubbles and coherent interactions of their individual scattered fields. This method is base

The effective medium method is used to investigate resonance scattering from schools of fish with gas-filled swim bladders, as a function of frequency and azimuth. Calculations are also performed with a coupled differential equation model, which inco

A time-domain computational model is used to describe the dynamic evolutions of fish schools. The individual and ensemble fish behaviors are governed by three radial parameters, representing attraction, orientation, and repulsion zones between fishes

The air-filled swimbladders of fish resonate like damped air bubbles, and are very efficient acoustic scatterers at low to mid frequencies (typically20 kHz). Scattering experiments were performed on an artificial "fish school" constructed from polyet

A model used previously to study collective back scattering from fish schools [Feuillade et al., J. Acoust. Soc. Am. 99(1), 196–208 (1996)], is used to analyze the forward scattering properties of these objects. There is an essential physical diffe

Assessing the validity of measurement/model comparisons in fisheries acoustics is difficult, due to the uncertainty in ground truth for acoustic measurements obtained in the open water. One way to overcome this is to utilize laboratory measurements,

A low cost biplanar reflector target has been developed and used in a system performance test of a near surface omnidirectional source and receiver. The target was constructed from sheets of closed cell plastic bubble sheeting. Theoretically, this ma

This paper presents a study of low-frequency sound scattering by an air bubble near a flat pressure-release surface. Using a self-consistent approach to describe multiple-scattering interactions, and a monopole approximation for the individual scatte
