Linear optoacoustic underwater communication
Applied Optics, 2005The linear mechanism for optical-to-acoustic energy conversion is explored for optoacoustic communication from an in-air platform or surface vessel to a submerged vessel such as a submarine or unmanned undersea vehicle. The communication range that can be achieved is addressed.

Underwater communications refer to wireless techniques for sending and receiving data below water. Messages can be transmitted either point to point or through a network of multiple nodes. Nodes can be mobile (e.g., underwater vehicles, autonomous or remotely operated) and/or static (e.g., submerged buoys).

Wireless Underwater Communications
Wireless Personal Communications, 2012The depths of the oceans have a high potential for future industrial development and applications. Robotic autonomous systems will greatly depend on a reliable communications channel with operators and equipment either performing joint operations or on the surface. However, communications must face harsh conditions that hinder the performance.

Underwater acoustic communications
Proceedings of Electro/International 1995, 2002In recent years, underwater acoustic (UWA) communications have received much attention as their applications are beginning to shift from military towards commercial. UWA communications are made difficult by the combined effect of multipath propagation and high temporal and spatial variability of the channel conditions.

Underwater communication system.
The Journal of the Acoustical Society of America, 2010When a pressure wave hits the sea bottom, or another object, reflected signal is transmitted back and is detected by the system. Transmission underwater is limited by frequency and other causes. Information lost can be measured in parameters like range, accuracy, and reliability. The sound radiated from a source is propagated in the water.

To test several types of voice and code signals, communication was carried on over the conventional submarine underwater telephone between two submerged submarines. The signals included normal speech, differentiated and clipped speech, quarter-speed speech, and multiple-tone Morse code.

Loop antennas for underwater communications
12th European Conference on Antennas and Propagation (EuCAP 2018), 2018In this paper, the performances of circular loop antennas for underwater communication, designed to work both in freshwater and seawater, are analyzed. Firstly, the attenuation and wavelength in both environments are evaluated with the goal of selecting the proper working frequencies, that are supposed to be 433.92 MHz in freshwater and 10 kHz in ...
