Supporting AUV localisation through next generation underwater acoustic networks: results from the field
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 ...
2017 CMRE Annual Report
This Progress Report describes the Centre’s unclassified technical accomplishments and outputs performed under the 2017 programme of work.
Distributed information fusion in multistatic sensor networks for underwater surveillance
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 ...
2010 Research and Technology Highlights
Target time smearing with short transmmissions and multipath propagation
In active sonar the target echo level is often estimated with a propagation model that adds all multipath arrivals. If the (post-correlator) transmitted pulse is short compared to the multipath time spread then there is ...
Oceanographic field estimates from remote sensing and glider fleets
This work investigates the merging of temperature observations from a glider fleet and remote sensing, based on a field experiment conducted in an extended coastal region offshore La Spezia, Italy, in August 2010. Functional ...
Adaptive underwater sonar surveys in the presence of strong currents
We consider the task of conducting underwater surveys with a sonar-equipped autonomous underwater vehicle (AUV) in environments with strong currents. More specifically, this topic is addressed in the context of mine ...
Moving JANUS forward: a look into the future of underwater communications interoperability
In the past 8 years, the Centre for Maritime Research and Experimentation (CMRE) has developed, tested and promoted JANUS - a robust and simple modulation and coding scheme to be used as the first standard to support ...
CMRE 60th anniversary 1959 - 2019
This book has been published in recognition of the significant accomplishments achieved by the Centre of Maritime Research and Experimentation over the past 60 years. Thank you to the Centre's staff, scientists, engineers, ...
