Investigation of the acoustic source characteristics of high energy laser pulses models and experiment
… experimental data including photographs and hydrophone measurements as well as numerical calculations of expected pressures, bubble dynamics, and pulse shapes. The goal of this thesis was to investigate the characteristics of the laser generated acoustic pulse further through experimentation …

Application of the Method of Least Squares to a Solution of the Matched Field Localization Problem with a Single Hydrophone
The single hydrophone localization problem is considered. Single hydrophone localization is a special case of matched field localization where measurements from only one hydrophone are available. The time series of the pressure at the hydrophone is compared with predicted times series calculated …

Acoustic Radiation Force on a Fluid to Fluid Boundary by Phase Plate Focused Ultrasound
… were characterized experimentally by scanning hydrophone measurements and by numerical simulations. The results shogood agreement with each lens type. A theoretical framework for the focusing efficiency of fraxicon and Fresnel phase plate lens was also developed which compared well to the …

Experimental Design, Data Analysis, and Modeling for Characterizing the Three-Dimensional Acoustic Field of a Seismic Airgun Array
… 2000, and 5000 m. Calibrated acoustic pressure measurements collected during the experiment were analyzed to obtain zero-to-peak sound pressures, sound exposure levels, and pressure levels in 1/3-octave frequency bands. In addition, the experimental data were modeled by using a modified …
