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)

‘Killer’ AUV Sonar System

In January 2001, C&C Technologies (C&C), a company based in Lafayette (Louisiana, USA), introduced the first commercially successful autonomous underwater vehicle (AUV) to the offshore industry. The AUV’s survey sensor suite, which included an EdgeTech side-scan sonar and sub-bottom profiler, performed well in the Gulf of Mexico and Brazilian offshore environments. However, West Africa proved more challenging – particularly for the sub-bottom profiler. C&C soon began searching for alternative technologies to provide better sub-bottom profiler penetration and higher resolution side-scan sonar imaging.Jim Chance, C&C Technologies (USA) Art Kleiner, EdgeTech (USA)<P> Narrator: Fast forward to the early autumn of 2004… C&C...

CHIRP Sidescan Sonar System

Falmouth Scientific, Inc. (FSI) has reached into its well of experience and knowledge to develop the HMS-624 digital CHIRP sidescan sonar system offering dual simultaneous 100/400KHz frequency operation. The HMS-624 provides imaging capabilities for deep and shallow water applications. The twofish electronics incorporate FSI’s CHIRPceiver 24-bit CHIRP signal processing, which results in very-high-resolution sidescan data at towing depths of up to 2,000 metres. The Topside Power/Data Multiplexer Interface is packaged in a standard 2U 19” rack mount enclosure and provides a 4Mb/s DSL connection for the towfish and a standard Ethernet connection for the data processing computer. The system uses... (read more)

Multibeam Sonar Training Course

The 51st UNB-OMB / UNH-CCOM Multibeam Sonar Training Course, co-hosted by the Directorate of Hydrography and Navigation, Brazilian Navy, will be held from 23-28 November 2009 at the Hotel Orizzonte, Niterói, RJ, Brazil and this will be first time the course has been conducted in South America.     The Multibeam Course is a 36-lecture, 6-day course primarily designed to provide a theoretical and practical background in marine multibeam survey technology and techniques. The information is tailored for those using marine multibeam survey systems in both the traditional hydrographic survey field (for safety of navigation and nautical charting) as well... (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)

Obstacle Avoidance Sonar

Sonardyne International, UK, has announced the launch of its new Navigation and Obstacle Avoidance Sonar, NOAS, at NAVDEX 2013 in Abu Dhabi. Designed for use on submersible vehicles, NOAS enables faster, safer and more efficient navigation by detecting and classifying potentially hazardous underwater obstacles in its path. Unveiled on the first day of the exhibition, NOAS provides a unique combination of very long range 2D navigation performance, 3D object detection and class leading intruder detection in a single compact sonar. In 2D mode NOAS provides the crucial long range navigation information enabling underwater vessels to steer a safe course. When... (read more)

Side-scan Sonar Demonstration

GeoAcoustics has launched Sonar 2094 Digital. A series of seminars and demonstrations were held by Simrad Spain, the local Kongsberg office, in November and December of the past year for their naval, scientific and industry customers. The capabilities of this technology for environmental mapping, engineering and archaeology surveys as well as object detection and classification were shown in various places along the Mediterranean coast.   Sonar 2094 Digital is the successor of the Dual Frequency Side-scan sonar, which was first launched in 1996 and developed into an industry standard, with over 1,000 units sold worldwide. Sonar 2094 Digital combines the... (read more)
