On adaptive underwater object detection
(NURC, 2012/04)
A new algorithm for the detection of underwater objects in sonar imagery is proposed. One particularly novel component of the algorithm also detects the presence of, and estimates the orientation of, sand ripples. The ...
Volumetric distribution of oceanographic fields estimated from remote sensing and in situ observations from autonomous underwater vehicles of opportunity
(NURC, 2012/04)
A main challenge of military oceanography (MILOC) is to assess the oceanographic conditions of denied/highrisk marine regions. Monitoring technologies are limited to those that can provide access to these regions. Remote ...
Antisubmarine warfare applications for autonomous underwater vehicles: the GLINT09 field trial results
(NURC, 2012/05)
Surveillance in antisubmarine warfare (ASW) has traditionally been carried out by means of submarines or frigates with towed arrays. These techniques are manpower intensive. Alternative approaches have recently been suggested ...
Adaptive autonomous underwater vehicles for littoral surveillance: the GLINT10 field trial results
(NURC, 2012/05)
Autonomous underwater vehicles (AUVs) have gained more interest in recent years for military as well as civilian applications. One potential application of AUVs is for the purpose of undersea surveillance. As research into ...
A data-driven control strategy in synergy with continuous active sonar for littoral underwater surveillance
(CMRE, 2017/11)
In this work, we describe a data-driven Mission Management Layer (MML) running on-board AUVs which manages the phases of a littoral surveillance mission and exploits the characteristics of Continuous Active Sonar (CAS) ...
GLider Acoustics Sensing of Sediments (GLASS): experiments and data analysis
(CMRE, 2013/12)
Seabed characteristics (geoacoustic properties and scattering strength) are critical parameters for sonar performance predictions. However, this bottom information is considered very difficult and expensive to achieve in ...
Efficient dense sonar surveys with an autonomous underwater vehicle
(CMRE, 2014/01)
An algorithm for the in situ adaptation of the survey route of an autonomous underwater vehicle (AUV) equipped with side-looking sonars was recently proposed. This algorithm immediately exploits the through-the-sensor data ...
AUV-enabled adaptive underwater surveying for optimal data collection
(NURC, 2012/04)
A new adaptive strategy for performing data collection with a sonar-equipped autonomous underwater vehicle (AUV) is proposed. The approach is general in the sense that it is applicable to a wide range of underwater tasks ...
Supporting AUV localisation through next generation underwater acoustic networks: results from the field
(CMRE, 2017/11)
This work describes how the localisation of autonomous underwater vehicles can be supported through net-worked acoustic communication. The localisation approach in-cludes timing information within acoustic messages to ...
Distributed information fusion in multistatic sensor networks for underwater surveillance
(CMRE, 2017/11)
Surveillance in antisubmarine warfare has traditionally been carried out by means of submarines or frigates with towed arrays. These techniques are manpower intensive. Alternative approaches have recently been suggested ...
