Kraken Joins Forces with US Navy for SAS Sensor Research
Kraken Robotics has signed an agreement with Naval Undersea Warfare Center Division (NUWC) in Newport to conduct joint research into advanced signal processing techniques for the current and future generation of Synthetic Aperture Sonar (SAS) sensor technologies.The cooperative research and development agreement signed between the parties also includes exploration into enhanced image processing techniques such as data fusion, image registration, multi-spectral image enhancement and automated target recognition.Kraken Robotics has engaged in several similar R&D agreements with U.S. government

to the internet in real time, and its implications are huge. It will help ensure that offshore construction is sensitive to marine mammal activity and will enable the monitoring of marine protected areas through the real time recognition of illegal fishing activity.”Professor of Statistical Signal Processing Paul White, from the University of Southampton, said: "Using the power of artificial intelligence to monitor sound in the underwater world, combined with the ability to rapidly relay information ashore, will enable us to provide tools to protectfragile marine ecosystems and detect a range

of it will be reflected back to the interrogator (a phenomenon known as Rayleigh backscattering). As pressure waves from an acoustic emission impose “nano strains” on the fiber, it causes fluctuations in the reflected light. These fluctuations can then be analyzed and, using advanced signal processing, translated into a unique acoustic signature resulting not only in the detection, but identification and even localization of the source. When DAS is used in a marine environment, the defects along the fiber essentially act as tiny hydrophones, transforming a length of fiber optic cable into

source, a D11 transducers to mimic machinery noise, and tracked AIS so they could correlate it with acoustic data from the hydrophones and the glider’s location data.Burnett says one of the goals was real-time processing to get real-time information about what’s in the water. This meant signal processing and software integration into the glider, but, with the longer array, also improving the power supply to reduce noise.“We were able to correlate with AIS and could see a cargo vessel passing within 2.45nm of the array,” says Burnett. “We were also able to collect biological

Seagrass Monitoring to the Fore in South West England
for the first time in May this year, is set to change the way seagrass meadows are monitored in the future, complementing traditional diver surveys to cover much larger areas and enable rapid re-survey work as required.Image credit ValeportThe VA500 altimeter, which uses state-of-the-art signal processing, was customized by the instrument manufacturer for this project. Jim Gardiner, Research Scientist at Valeport said: “The VA500 altimeter was developed to deliver reliable underwater range measurements in a compact, robust package. Working with University of Plymouth and HydroSurv, custom

for air. And a lot of our competitors that do the ultrasonics in air don’t have the underwater experience, longevity or capability that we have. Embracing all of that and embracing the science of sound itself has been very important. A lot of people focus more on the electronic or the signal processing side; we focus on design and the construction of the transducers.”Holistic is also an apt description for the way in which Massa helps to engineer solutions for its client’s needs, as it’s far more than simply developing technology for the sake of technology. “We also
