Multiple-Aspect Acoustic Scattering from Fluid-Filled Cylinders Measured at Sea

摘要

Multiple-aspect backscattering is studied at low-intermediate frequency from fluid-loaded, fluid-filled, thin-walled cylinders. The dynamics of predicted elastic waves are described in the frequency-aspect domain by extending to liquid-filled shells the thin-shell theory originally developed for air-filled shells. The models are validated by at-sea measurements of a water-filled cylinder.
