Single Acoustic Transducer with Adaptative Radiation Pattern for Underwater Networks

Underwater acoustic networks are constrained by low bandwidth, long propagation delays, multipath, and spatially distributed interference, namely due to neighboring nodes. Directional transmission can improve the signal-to-interference-plus-noise ratio and increase spatial reuse, but conventional phased arrays are ofte...

Multiplexing of Circular and Spiral Acoustic Fields with Low Cross-Correlation Signals for Underwater Localization

The use of underwater spiral acoustic fields is a promising approach for underwater unmanned vehicle (UUV) localization. This technique relies on the transmission of both circular and spiral acoustic fields, enabling the estimation of the departure bearing angle through their phase difference. However, the accuracy of...
