Beamforming and subsurface source localization in bearing, range and depth
MetadataShow full item record
This thesis serves as a satisfactory introduction to the use of beamforming to localize an underwater source of acoustic energy in bearing, range and depth, including the necessary background material in acoustics and computation. Plane wave beam-forming is introduced, as is beamforming with a Pekeris waveguide and a waveguide with a depth dependent sound velocity profile. Under certain circumstances the filtering of unwanted signals is considered, and throughout the thesis a heavy emphasis is placed on the theory of linear algebra and its implications to the beamforming process.
