Abstract This paper presents the development of an Autonomous Undersea Vehicle (AUV) that is capable of an acoustically stealth delivery of a payload. The payload is composed of a black box noise maker and the goal of this “stealth mission” is to minimize the amplitude of the acoustic signal emitting from the noise maker ...

Underwater docking of autonomous undersea vehicles using optical terminal guidance
Oceans '97. MTS/IEEE Conference Proceedings, 2002Missions in which an autonomous undersea vehicle docks with an underwater node for the purpose of battery recharging and/or data transfer greatly increase the scope of potential applications possible with UUVs. Robust and accurate vehicle guidance to a small, simple and reliable docking structure is a critical capability which must be developed in ...

An integrated computational model of an autonomous, visually guided undersea vehicle
Proceedings of 1994 3rd IEEE International Workshop on Robot and Human Communication, 2002This paper reports progress made on the development of a computational model of a visually guided autonomous underwater vehicle. The model is based on knowledge obtained from laboratory studies in psychophysics and neurophysiology as well as on new developments in computer science.

Proceedings of the 10th International Conference on Underwater Networks & Systems - WUWNET '15, 2015
In an effort to address innovative applications for underwater networks, we present an autonomous bi-static configuration of vehicles demonstrating the future need for successful underwater communication. Specifically, this work addresses improving undersea multiple target track (MTT) estimation by improving sensor location management for multi-static ...

The Journal of the Acoustical Society of America, 2009
Spatial variability of the seabed in littoral regions is driven by processes that span a large range of space and time scales, ranging from eustatic fluctuations which are more or less global in extent but can have a profound effect on sedimentary layering from hundreds of meters to sub-meter scales, to biologic reworking which might be very local and ...

Acoustic reverberation in littoral ocean waveguides is often controlled by small-scale seabed heterogeneities. Thus, validation of reverberation models and development of realistic simulations require measurements of those scales. Clutter features for mid-frequency active sonars span scales from order 1–1000 m.

The law governing autonomous undersea vehicles: what an operator needs to know
Proceedings of OCEANS 2005 MTS/IEEE, 2005AUVs are the cutting edge of technology used to explore the world's oceans. Unlike tethered and remotely operated vehicles which are a simple extension of the research vessel, AUVs are, and legally should be, considered separate entities. The AUVs autonomous nature, however, creates a regulatory gap.

This paper presents the results of the experimental evaluation of three radio frequency (RF) modems for use as communication infrastructure among multiple surfaced cooperating autonomous undersea vehicles (AUVs), gateway buoys, and land or ship based operators. RF modems are inherently more complex than their wired counterparts which makes it difficult
