Abstract:

Numerical results demonstrate that both Fraunhofer and Fresnel diffractions provide good approximations to forward scattering by elastic spherical shells and rigidsoft spheres, for non-dimensional frequency values 5 or ka or 40 and scattering angles 0 deg or 0 or 10 deg. The calculations were done for the far field, with incident plane waves. Signal processing, Classification, Antisubmarine warfare, Underwater acoustics.
