Abstract
The target strength of thin spherical and cylindrical elastic shells, either air- or water-filled, has been calculated in order to assess the effects of penetrability of the shell material on the scattering process. Calculations have been performed using both the Kirchhoff method and the Watson-Sommerfeld transformation of the Rayleigh normal-mode series. The contribution of specular reflection from the vertex can be separated out in either method, and distinguished from shadow-boundary reflections or creeping-wave contributions. Similarly as in the normal-mode calculations of Diercks and Hickling [J. Acoust. Soc. Amer. 41, 380 (1967)], the penetrability effects were found to be considerable.
