Sentinel Sonar Order

The US Naval Underwater Warfare Center (NUWC) in Rhode Island (USA) has placed a contract with Sonardyne Inc., Houston (TX, USA) for the supply of an additional Sentinel Intruder Detection Sonar system.     The announcement follows the completion of rigorous acceptance and readiness trials by NUWC in 2008 when Sentinel was shown to meet the US Navy's performance requirements for diver detection. The latest contract adds an additional Sentinel to the new Integrated Swimmer Defence System. This is being led by the Program Executive Office, Littoral Mine Warfare (PEO-LMW - PMS480) and the first Sentinel was delivered to NUWC... (read more)

Synthetic Aperture Sonar Challenges

Synthetic aperture sonar (SAS) has been under active development for decades. The technique is particularly well suited for autonomous underwater vehicles, and it is expected that SAS will replace traditional side-scan sonars for many ‘high-end’ AUV applications in the years to come. Research systems have been used for more than 15 years and many R&D groups around the world have been able to present images that would not have been possible to produce using traditional sonars. However, in many cases, these impressive sonar images are the result of days of tuning and tweaking by experts. A lot of effort has... (read more)

Sonar Interface Unit

The Octopus 160 sonar interface unit's design and is compact, rugged and weather-proof. Compatible with EdgeTech's work-horse 272TD dual-frequency side-scan sonar, it is simple to operate and is suitable for small boat use in many types of underwater survey. Housed in a rugged custom Pelicase, the 160 is highly portable and it can be operated with the lid closed allowing uninterrupted operation in harsh environments.   Another popular feature is the new user interface for all controls and once configured for a specific towfish, this needs no further adjustment. With direct connection to standard EdgeTech 272TD tow cables and full... (read more)
