DOLPHIN: Enabling Technology for Acoustic Systems

. In other words, DOLPHIN SAS can at least double the standard SAS speed. It can even increase the speed, albeit with an increasing blurry image.  Figure 6 was created in a test tank with a simple DOLPHIN SAS operating at 3x the Nyquist speed.In 2018 QNA was awarded a contract from the Naval Surface Warfare Center, Panama City Division, (NSWC PCD), Panama City, FL to demonstrate advanced, low power, sidescan sonar technology. Phase 1 is complete and results will be presented in future publications.Figure 5: Two sonar swaths overlapping with DOLPHIN™ processing fill the typical nadir gap. Image:

to use, and I have no doubt it’s going to streamline efficiency.”Throughout the process of the development of the SBDA 100, ONR TechSolutions has worked in conjunction with Space and Naval Warfare Systems Command (SPAWAR) Atlantic; industry partner Intelligent Automation Inc.; and Naval Surface Warfare Center (NSWC) Panama City, which is the home of the U.S. Naval Diving and Salvage Training Center. SPAWAR served as the principal investigator and NSWC Panama City provided technical support and hosted the training and demonstration of the SBDA 100 at sea.“The technology has tested very

Sonardyne Aids US Navy Underwater Vehicle Testing

Underwater target tracking technology from Houston-based Sonardyne Inc., has been chosen by the U.S. Naval Surface Warfare Center (NSWC), Carderock Division for testing subsea systems and underwater vehicles in development for the Navy and wider maritime industry.Located in Maryland, Carderock Division is the U.S. Navy's research, engineering, modelling and test center for surface and undersea technologies. It is the largest, most comprehensive establishment of its kind in the world. Thanks to its proximity to the Gulf Stream, Carderock’s South Florida Ocean Measurement Facility (SFOMF)

The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the U.S. Navy in Memphis since 1991. This facility is well designed for a wide variety of hydrodynamic and hydroacoustic tests. Its overall size and capabilities allow test-model Reynolds numbers to approach, or even achieve, those of full-scale air- or water-borne transportation systems. (Photo: U.S. Navy)

Navy Tests Scale Models in Big Facilities

Inside Naval Surface Warfare Center, Carderock DivisionThe Naval Surface Warfare Center, Carderock Division in West Bethesda, Md., is one of the world’s leading centers for surface and underwater hydrodynamic expertise, research and design, to include world-class facilities for experimentation, testing, evaluation and validation.“We build scale models of ship designs and can test these hull forms in our facilities to measure hydrodynamic load on the structure or evaluate seakeeping abilities,” said Mike Brown, head of Carderock’s Naval Architecture and Engineering Department.

that may serve as a mobile coastal monitoring system, as well as training and education of graduate and undergraduate students in ocean engineering.   The project will leverage and collaborate with FAU’s ongoing Naval Engineering Education Consortium effort in conjunction with the Naval Surface Warfare Center, Panama City, which involves use of two unmanned underwater vehicles (UUV) for adaptive subsurface sensing in support of detection of objects on the sea bottom. “Fostering collaborative partnerships in scientific research is essential to ensuring that the United States remains at

UUV Manufacturer Aims Big by Going Small

.   In March 2016 the first three production micro-UUVs were delivered to SPAWAR Systems Center - Pacific. These vehicles were configured with a flooded payload module to enable rapid payload development and demonstration.   In July 2016 six micro-UUVs were delivered to the Naval Surface Warfare Center Panama City Division (NSWC PCD). These vehicles were configured with a dry payload volume that will enable the Navy to test various new sensor systems with these small flexible vehicles.   During the week of Aug. 22-26, 2016 Department of the Navy scientists and engineers collaborated

With the support of the U.S. Navy, the finalist teams tested their prototype devices at the nation's most advanced wave-making facility, the Naval Surface Warfare Center's Maneuvering and Seakeeping Basin at Carderock, Md.   “This competition set a difficult threshold of doubling the energy captured from ocean waves, and four teams surpassed that goal,” said Lynn Orr, DOE’s Under Secretary for Science and Energy. “AquaHarmonics&rs
