Abstract:

Three-dimensional angular distributions are calculated for rigid, soft, and elastic spheroidal targets. The elastic targets also include resonance locations and the results for the predictions of the three classes of targets are compared at both resonance values for the elastic target and nonresonance values. Both similarities and differences of the patterns are outlined over a broad frequency range and explained. Keywords Acoustic scattering, Shallow water, Waveguide propagation.
