Abstract:

The scientific rationale for SPACE is that even though reliable underwater acoustic communication is central to the Navys vision and Concept of Operations CONOPS for the future, and while significant progress in communications system development has been made in the last 15 years, current 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, SPACE brings together a team of 10 investigators with world leading 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.
