It can be seen from the results that when scattering angle varies from [[theta].sub.s] = 0[degrees] to [[theta].sub.s] = 90[degrees], scattering from both ship and coupling interaction preponderate in the total scattered field because of dihedral reflectors on the ship and dihedral reflectors formed by flank of the ship and the sea surface.
