A Model of Acoustic Backscatter from Arctic Sea Ice.

Abstract

A mathematical model of acoustic backscatter from Arctic Sea ridge keels is developed. The model is demonstrated to produce good agreement with data. It is a composite surface scattering theory based on diffractive scattering from small scale roughness on the flanks of randomly oriented triangular ridge keels. Keywords: Sea ice; Ice ridge keels; Underice; Acoustic scattering; Underwater acoustics.
