Sound propagation around underwater seamounts
(Massachusetts Institute of Technology, 2005)
This thesis develops and utilizes a method for analyzing data from the North Pacific Acoustic Laboratory's (NPAL) Basin Acoustic Seamount Scattering Experiment (BASSEX). BASSEX was designed to provide data to support the ...
Physically constrained maximum likelihood (PCML) mode filtering and its application as a pre-processing method for underwater acoustic communication
(Massachusetts Institute of Technology, 2009)
Mode filtering is most commonly implemented using the sampled mode shape or pseudoinverse algorithms. Buck et al [1] placed these techniques in the context of a broader maximum a posteriori (MAP) framework. However, the ...
Lossy compression and real-time geovisualization for ultra-low bandwidth telemetry from untethered underwater vehicles
(Massachusetts Institute of Technology, 2008)
Oceanographic applications of robotics are as varied as the undersea environment itself. As underwater robotics moves toward the study of dynamic processes with multiple vehicles, there is an increasing need to distill ...
