CALCULATIONS OF ACOUSTIC SCATTERING FROM THE OCEAN SURFACE

The problem of acoustic scattering from the ocean surface can be solved using the formalism that has been developed to describe the scattering of a wave off a finite object. A refined version of this formalism is used to generate various approximation schemes. The validity of these approximations are investigated and their relative merits are discussed. The scattering cross section is evaluated numerically and it is concluded that the observed cross section for scattering near the ocean surface cannot be explained by ocean surface scattering alone. © 1990, Acoustical Society of America.
