Improved Active Sonar Tactical Support by Through-the-Sensor REA

, 2011
Reverberation is a problem for active sonar operating in shallow waters, reducing detection probabilities and introducing false alarms. Within the European Defence Agency project Rumble-2, a demonstrator system has been developed for ”through the sensor”

Northern bottlenose whales in a pristine environment respond strongly to close and distant navy sonar signals

, 2019
Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant sound sources with lower ...
