Characterization of underwater target geometry from autonomous underwater vehicle sampling of bistatic acoustic scattered fields
(Massachusetts Institute of Technology, 2015)One of the long term goals of Autonomous Underwater Vehicle (AUV) minehunting is to have multiple inexpensive AUVs in a harbor autonomously classify hazards. Existing acoustic methods for target classification using AUV-based ... -
The choreography of belonging : toothed whale spatial cohesion and acoustic communication
(Massachusetts Institute of Technology, 2016)To maintain the benefits of group membership, social animals need mechanisms to stay together and reunite if separated. This thesis explores the acoustic signals that dolphins use to overcome this challenge and mediate ... -
Evaluation of vector sensors for adaptive equalization in underwater acoustic communication
(Massachusetts Institute of Technology, 2014)Underwater acoustic communication is an extremely complex field that faces many challenges due to the time-varying nature of the ocean environment. Vector sensors are a proven technology that when utilizing their directional ... -
Progressively communicating rich telemetry from autonomous underwater vehicles via relays
(Massachusetts Institute of Technology, 2012)As analysis of imagery and environmental data plays a greater role in mission construction and execution, there is an increasing need for autonomous marine vehicles to transmit this data to the surface. Without access to ... -
Quantification of the spatial and temporal evolution of stratified shear instabilities at high Reynolds number using quantitative acoustic scattering techniques
(Massachusetts Institute of Technology, 2015)The spatial and temporal evolution of stratified shear instabilities is quantified in a highly stratified and energetic estuary. The measurements are made using high-resolution acoustic backscatter from an array composed ...
