High Frequency Sonar Elastic Image Enhancements: Ray Theory
Abstract
Research is reported on the causes of large high frequency acoustic echoes from tilted bluntly truncated cylinders in water. As a consequence of the cylinder's tilt, the specular reflection by the cylinder's outer surface only weakly contributes to the backscattering. All of the enhancements considered are associated with the target's mechanical response. An enhancement is discovered and analyzed for plastic and rubber cylinders usually considered to have weak backscattering. Helical contributions for cylindrical shells were also studied.
