Preliminary Modeling of Acoustic Detection Capability for the Drifting Arctic Monitoring System
Abstract
The Arctic Ocean is a region of interest for Canadian defence. Here, a concept for a set of long-lived drifting acoustic monitoring arrays is proposed. The detection performance of this concept, the Drifting Arctic Monitoring System, or DAMS, is investigated via modelling. It is found that in very quiet conditions, such as that found under ice cover, detection ranges of hundreds of kilometres are possible. On the other hand, in the presence of ice cracking or other intensely noisy phenomena, DAMS is not likely to function as well. The limitations imposed by this noise could however be mitigated by a more complete picture of the nature of the ambient noise that is likely to be encountered, therefore a better understanding of the Arctic ambient noise environment is an important part in the development of the system. This could make the DAMS concept an important part of an underwater surveillance network.
