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)

Edgetech Sonar Demonstrated

EdgeTech is to demonstrate the latest technology in side-scan sonar and swath bathymetry at the upcoming US Hydro 2011 Conference in Tampa, Florida, from 25th to 28th April. EdgeTech's vessel, the Ocean Research II, will be outfitted with various equipment. EdgeTech's 4600 combines the high resolution 2D capabilities of a side-scan sonar with the 3D imagery of a multi-beam echo sounder. The result is a highly effective survey tool that produces real-time high resolution 3D maps of the seafloor and is simple to use and cost-effective. The 4200 is EdgeTech's most versatile side-scan sonar system and can be configured for... (read more)

Successful Sonar Software Workshop

Chesapeake Technology recently hosted over 63 professionals for a hands-on training seminar focusing on the use of sidescan and sub-bottom sonar software. The three-day event held in the Charleston (South Carolina, USA) area was CTI's third annual workshop for underwater survey professionals. The training included two four-hour sessions aboard the Silver Crescent, a research vessel provided by South Carolina's Department of Natural Resources. As the participants experienced the field exercise aboard the Silver Crescent, the ship simultaneously towed two sidescan sonars. Both systems, a Klein System 3900 (courtesy of L-3 Klein) and a Marine Sonic Sea Scan PC system... (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...

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 Demonstrations

During Ocean Business 2009, L-3 Klein will be running live demonstrations of the L-3 Klein System 5000 V-2. The demonstrations will be conducted on-board the Bill Conway on Tuesday, 31st March at 1530, Wednesday, 1st April at 1400 and Thursday, 2nd April at 1030. The L-3 Klein System 5000 V2, with the added swath bathymetric capability, employs advanced Interferometric signal processing to produce simultaneous estimates of the seabed topography out to the full swath extent of the sonar, typically 10 to 12 times the overall altitude of the tow fish. This added seabed topographic measurement is post processed... (read more)

Didson Next-generation Sonar

Sound Metrics Corp, UK, the manufacturer of the high-resolution Didson multi-beam sonar, has developed its next-generation sonar, ARIS (Adaptive Resolution Imaging Sonar). The ARIS uses the same Didson technology to produce crisp and clear images. During Oceanology International, the Sound Metrics Corp featured the ARIS 3000 mounted to an X2 rotator in a water tank. With 128 beams operating at 3MHz, the ARIS Explorer 3000 collects more data than any other imaging sonar in its class. All of the ARIS Explorer models work in zero-visibility conditions and are built to deliver in the most challenging conditions. In addition, the small... (read more)
