Bubbles and Acoustic Communications Experiment (SPACE08): Acoustical and Physical Characteristics of Diffuse Bubble Plumes

摘要

The scientific rationale for this project is that current underwater acoustic communication techniques fall far short of what is needed in terms of the data rates, the range of environments and operating conditions, and levels of covertness at which reliable communication links can be established. For example, communications in very dynamic environments (e.g., surface scattered environments in rough weather, communications at depth and speed for submarines) or at low SNRs as required for covert communications are areas where progress is still needed. To bridge the gap between current capabilities and future requirements, an experiment was conducted at Marthas Vineyard Coastal Observatory (MVCO) in the fall of 2008 by a team of investigators with expertise in physical oceanography, underwater acoustics, signal processing, information theory and coding, practical modem development, Navy CONOPS and assets, and in the use of autonomous and distributed systems.
