Feasibility Study on Unmanned Aerial Vehicle-Based Undersea Acoustic Sensing

Journal of Oceanography and Marine Research, 2019
An unmanned aerial vehicle (UAV) system with hybrid air-water quadcopter platform, named AquaQuad, was developed in the Department of Mechanical and Aerospace Engineering, Naval Postgraduate School. It can land on ocean surface with different sea-states for communication and provide undersea passive acoustic sensing.

Unmanned Undersea Vehicles: An Asymmetric Tool for Sea Denial

2008
Abstract : One of the most salient trends in military technology is the growing prominence of unmanned vehicles. Much has been written about Unmanned Air Vehicles (UAVs), and a fair amount about Unmanned Surface and Unmanned Ground Vehicles (USV/UGVs). In contrast, very little has been written about Unmanned Undersea Vehicles (UUVs).

An acoustic lens sonar using micromechanical hydrophones for unmanned undersea vehicles

Proceedings of the 1992 Symposium on Autonomous Underwater Vehicle Technology, 2003
The system design of an acoustic lens sonar using micromechanical hydrophones is examined for a mission as the forward-looking sonar on an autonomous underwater vehicle (AUV). Micromechanical hydrophone technology combined with an acoustic lens system can provide a high sensitivity, high resolution imaging sonar system. As the micromachining technology
