The mid-frequency scattering properties of three different cylindrical
shell models have been evaluated experimentally to study the influence of
resiliently mounted internal structures and typical structural discontinuities
such as endcaps and transverse stiffeners. The models consist of an empty
shell, and unequally spaced ring-stiffened shell, and a ring-stiffened shell
with resiliently mounted, wave-bearing internal structural elements. The
measurements were conducted over a frequency range of 2.75
