Description
Summary:This report considers high frequency (10-100 kHz) acoustic backscattering from the underside of sea ice from a fundamental physical point of view. The underice acoustic backscatter problem involves several issues in wave propagation and scattering not typically encountered in backscattering from other geophysical media (e.g., the ocean surface and floor). It is thus of intrinsic scientific interest, as well as being of vital interest in underwater acoustic applications.
