A Model of Acoustic Backscatter from Arctic Sea Ice.

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 r...
