Multiple scattering effect in acoustic response from a bubble cloud

摘要

An implementation of the acoustic multiple scattering between bubbles in a bubble cloud to model the cloud response to an active sonar signal is described. The bubble cloud is modelled as an aggregation of identical omnidirectional point scatterers. The acoustic scattering strength of the scatterers is calculated from the physical properties of bubbles. The dependence of the multiple scattering effect on air volume fraction, sonar frequency, and the bubble size is investigated.
