Terrain mapping with forward looking sonar on unmanned underwater vehicles
(NATO. SACLANTCEN, 1997)
In the future, successful reconnaissance operations conducted in shallow water with Autonomous Underwater Vehicles will rely heavily on a high performance, high resolution, forward look sonar coupled with terrain mapping ...
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 ...
Real-time clock synchronisation in underwater acoustic networks
(CMRE, 2019/06)
This paper proposes an algorithm for real-time clock synchronisation in underwater acoustic networks. The algorithm models modem clocks as linear functions and embeds the data necessary for the clock synchronisation procedure ...
A market-based task allocation framework for autonomous underwater surveillance networks
(CMRE, 2019/06)
Realisation of underwater robotic surveillance networks raises several challenges for marine robotics. The underwater scenario is typically characterised by intermittent and unreliable communication. This makes it challenging ...
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 ...
AUV active perception: exploiting the water column
(CMRE, 2019/06)
Autonomous Underwater Vehicles (AUVs) present a low-cost alternative or supplement to existing underwater surveillance networks. The NATO STO Centre for Maritime Research and Experimentation is developing collaborative ...
A distributed framework for embedded collaborative autonomy
(CMRE, 2019/05)
We have designed and implemented a framework for the development and deployment of multi-agent task allocation solutions, with particular awareness of the operational constraints encountered by Unmanned Maritime Systems ...
An autonomous underwater vehicle data-driven control strategy for target tracking
(CMRE, 2019/05)
This paper presents a data-driven approach to control the movement of autonomous underwater vehicles (AUVs) operating as receivers of a multistatic sonar surveillance network. The algorithm adopts a nonmyopic receding ...
