A modem design for underwater acoustic networking in the High North
(CMRE, 2019/05)
We design a software modem for long range underwater acoustic communications in ice-covered oceans. The modem is equipped with three coded modulation schemes achieving 1.8, 21.4 and 96.2 bps, respectively. In addition, we ...
Experimental evaluation of Net-LBL: an acoustic network-based navigation system
(CMRE, 2019/06)
This paper describes the use and in-field evaluation of a Networked-Long Base Line system (Net-LBL) where a network of underwater nodes cooperate to support the localisation and navigation of mobile vehicles. To avoid the ...
Dynamic underwater sensor network for sparse field estimation
(CMRE, 2019/06)
A coordinated dynamic network of autonomous underwater gliders to estimate 3D environmental sparse fields is proposed and tested. Field spatial sparsity is exploited in the estimation algorithm. Moreover field measurements ...
Toward the development of secure underwater acoustic networks
(CMRE, 2019/05)
Underwater acoustic networks (UANs) have been recognized as an enabling technology for various applications in the maritime domain. The wireless nature of the acoustic medium makes UANs vulnerable to various malicious ...
Scalable adaptive multitarget tracking using multiple sensors
(CMRE, 2019/06)
In networked mobile multitarget tracking systems, parameters such as detection probabilities, clutter rates, and motion model parameters are often unknown and time-varying. Such parameter variability can seriously degrade ...
Multistatic sonar: a road to a maritime network enabled capability
(NURC, 2007/10)
NATO's operational requirements emphasize interoperability of platforms participating in coalition task forces. Intelligently fusing data of multiple sensor systems and the development of adapted tactics are necessary steps ...
Heterogeneous underwater networks for ASW: technology and techniques
(NURC, 2008/06)
NATO's research and technology objectives for anti-submarine warfare (ASW) include persistent scalable heterogeneous wide-area surveillance networks for the littoral environment. Network and system design considerations ...
Secure underwater acoustic networks: current and future research directions
(CMRE, 2019/06)
Underwater Acoustic Networks (UANs) are widely used in various applications such as climate change monitoring, pollution control and tracking, tactical surveillance and offshore exploration. However, limited consideration ...
Autonomous networked anti-submarine warfare research and development at CMRE
(CMRE, 2019/06)
CMRE has been evaluating the potential of autonomous networked ASW using underwater vehicles through a program of sonar signal processing, underwater communications, navigation and robotic behavior developments and at-sea ...
Collaborative multistatic ASW using AUVs: demonstrating necessary technologies
(NURC, 2009/12)
Many research laboratories and several nations are showing an interest in the 'underwater networked battlespace' in which a combination of stationary and mobile underwater platforms communicate wholly or partially by the ...
