Abstract
This thesis is a documentation of the acoustical subsystems in the
DUMAND (II)
(Deep Underwater Muon
And Neutrino Detector)
astrophysical observatory to date (June 1993).
DUMAND will be deployed at 4800 m depth in the Pacific Ocean approximately
25 km off the west coast of the Island of Hawaii, starting in the fall
1993. Its goal is extra-galactical neutrino detection with an accurate
angular source directivity location of 1° or better. Caused by the
nature of the underwater detector installation, an acoustical positioning
system with resolution of 10 cm or better is required. The documentation
also includes brief descriptions about the theory of underwater acoustics,
matched filtering techniques and digital signal processing (DSP)
applications.
