AUV-Based Side-Scan Sonar Real-Time Method for Underwater-Target Detection
Journal of Marine Science and Engineering, 2023 The limitations of underwater acoustic communications mean that the side-scan sonar data of an autonomous underwater vehicle (AUV) cannot be transmitted back and processed in real time, which means that targets cannot be detected in real time. To address

Adaptive Underwater Acoustic Communications [PDF]
, 2010 Underwater wireless networks consist of mobile and static nodes, which usually communicate using the acoustic channel since radio transmissions attenuate rapidly and optical communication is only suitable for short distances. The underwater acoustic channel is plagued with issues of high transmission power requirements, rapidly changing channel ...
