DEWARS – Deep Water Acoustic Range System
The Deep Water Acoustic Range System (DEWARS) provides Noise levels and Spectrum levels measures in a real and controlled scenario of Surface Vessels and Submarines (including periscope, snorkeling and immersion depth).
These measures allow to:
- Establishing noise levels of the ship in different operational conditions, such as patrol speed, ultra quite speed and inception speed. In the case of submarines with different machinery speeds and depths.
- Establishing the status of the vessel within its class.
- Developing and validating studies for signature reduction and mathematical influence propagation models.
- Provide a Signature Database to record and retrieve recorded information of a ship:
- Ship characteristics and metadata.
- Broadband noise analysis.
- Narrowband noise analysis.
This type of information is useful to know the overall maintenance of ship, and possible machinery anomalies may be identified.
Signature reduction should be the objective once knowing the noise characteristics of a ship are known, understanding that the impact on the counter detection distance could be the difference of surviving an attack. Noisy ships are the “bells” of a fleet. Propagation models will let any Navy to define how noisy ships will be affected by the counter detection distances.
The Portable Deep Water Noise Range (DEWARS) minimum configuration is composed by:
- A hydrophones array.
- A communication buoy.
- A Control Unit for signal acquisition and processing.
- DGPS system for surface tracking data.
SAES is a worldwide recognized company that have supplied the latest signatures acquisition systems which have the benefit of an efficient and innovative processing technology and high operational availability, paramount features which are demanded by the maintenance policies of the new market.
