- Abstract
We study the influence of a bottom-sediment layer on the spatio-temporal structure of wideband acoustic pulses in shallow sea. The shallow sea is modeled as a uniform liquid layer above a layer of liquid sediments located on an elastic half-space. The influence of various acoustic parameters of the problem, in particular the thickness of the sedimentary layer, damping parameters, etc. on the structure of wideband pulses is considered. We analyze the features of constructive mode interference due to which the spatial structure of the pulses takes the form of beams.
