Abstract:A curved face hydrophone array has been designed, constructed, and tested for 20 000-ft-depth operations. A basic description of the hydrophone design, in which the hydrophone consists of a beamforming array of staves mounted on the circumference of a 20-in-diam. cylindrical housing, is presented. Since conventional pressure-release materials cannot be used in the construction, solutions to problems encountered, such as improper backing impedances for the individual elements and flexural waves genernated in th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
