Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	Knowledge of vocal tract area function is important for the understanding of phenomena occurring during speech production. We present here a new measurement method based on external excitation of the vocal tract with a known pseudo-random sequence, where the area…

Array element localization of a bottom moored hydrophone array
Barlee, Matthew; School of Earth and Ocean Sciences, University of Victoria, Victoria, BC V8W 3Y2, Canada - Dosso, Stan; School of Earth and Ocean Sciences, University of Victoria, Victoria, BC V8W 3Y2, Canada - Schey, Philip; Space Naval Warfare Center (SPAWAR), 53560 Hull Street, San Diego, CA 92152-5001, United States

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	In ocean acoustics, rapidly deployable, autonomous, bottom moored hydrophone arrays allow for quick, cost effective deployment, but result in poor knowledge of sensor positions. Because advanced array processing techniques, such as Matched Beam Processing, are highly sensitive to errors in…
