Intruder Alert: Ports Face a Range of Underwater Threats
the intruder detection system (IDS), which uses high-frequency active sonar to detect the presence of divers, SDVs, and increasingly small UUVs. Products such as the Forcys Sentinel, AquaShield from DSIT Solutions, and Norbit’s GuardPoint offer integrated solutions that combine sonar sensors, signal processing software, command-and-control interfaces, and even underwater loudhailers.These systems are typically arranged as networks of sonar nodes positioned along harbor entrances, piers, and critical infrastructure. Each sonar head scans a defined sector of the underwater environment, with overlapping
iBULe Photonics Unveils First 3rd-Generation Single Crystal Submarine Hydrophone
in underwater detection capability. By harnessing the enhanced properties of third-generation single crystal materials, the hydrophone delivers 9 dB greater sensitivity compared with conventional ceramic PZT hydrophones. This improved performance enables longer detection ranges and clearer signal processing, particularly in complex and noisy undersea environments.Designed for next-generation naval sensing systems and advanced ocean monitoring applications, the technology supports improved situational awareness and more precise acoustic detection for submarines and underwater platforms.During the

and naval vessels.A notable moment in RESON’s technological journey was its role in commercializing modern sonar technology, making multibeam sonar systems more compact, practical and accessible to surveyors worldwide. RESON also set early benchmarks in data quality through the adoption of advanced signal-processing techniques to enhance detection capability, maximize data accuracy and elevate seabed imaging clarity. RESON hydrophones are used in demanding commercial and defense applications, with many units still in active service more than three decades after installation.A hallmark of RESON is
Underwater Infrastructure Security Project Launched in Norway
, have clearly exposed the limitations of today’s largely ad-hoc and spatially limited monitoring approaches.INSURE will address this challenge by developing a cost-effective, long-range, and continuous monitoring solution based on Distributed Acoustic Sensing (DAS), combined with advanced signal processing, machine learning, and multi-source data fusion. By transforming existing fiber-optic cables into real-time sensing systems and analyzing underwater acoustic intelligence with vessel tracking data, INSURE enables early threat detection, precise geo-localisation, and predictive risk assessment
Vatn Systems Acquires Crewless Marine
Vatn Systems, a defense technology company building autonomous underwater vehicles (AUVs) for the US military, allied nations, and commercial customers, announced the acquisition of Crewless Marine, a Rhode Island-based company specializing in advanced underwater acoustic sensing and signal processing.Founded by former Navy engineers, Crewless Marine brings experience in torpedo acoustic systems, hydrophone manufacturing, and real-time signal processing. The acquisition strengthens Vatn's strategy to vertically integrate its tech stack to control critical technologies, reduce supply
NUWC Division Newport Hosts Warfighters Panel, ‘Cup O’ Joe’ to Celebrate Veterans
.”Cup O’ JoeAt the conclusion of the warfighters panel, Division Newport hosted its annual “Cup O’ Joe” event, which gives employees a chance to discuss their experiences in the military and swap stories over coffee.Among the attendees were Susan Balcirak, head of the Signal Processing and Analysis Branch, and her husband Dean Balcirak, head of the Information Customer Services Branch. The North Kingstown, Rhode Island, couple met during their freshman year at the U.S. Naval Academy when they were paired together on a boat for the sailing team. Dean, who grew up in the Great
KIMM Cracks the Code for Underwater Radiated Noise Prediction
methods, which require intermittent data collection using external equipment in quiet sea areas free from surrounding ship traffic, the new system enables continuous onboard monitoring with real-time updates. Even with a limited number of sensors, the optimized sensor placement and advanced signal processing techniques allow the system to maintain high prediction accuracy, achieving a margin of error within 4 decibels during real-world tests.The algorithm processes real-time data from accelerometers attached to the vessel’s hull, analyzing vibration characteristics, radiation efficiency,

revolutionize USV autonomy. Integrating real-time diagnostics with autonomous decision-making requires highly advanced algorithms and robust onboard computing, capabilities not yet fully matured or widely available.Acoustic sensing faces major challenges such as high ambient noise levels, complex signal processing requirements, and reliable integration into autonomy algorithm—all areas needing ongoing research and improvement
Teledyne Marine Unveils BlueStreamX2 Enhancement for Benthos Acoustic Modems
performance. This upgrade is now available across all Benthos modem families—Acoustic Telemetry Modem (ATM), Compact Modem (CM), and Ultra Compact Modem (UCM)—as well as on UTS topside systems.Benthos acoustic modems, known for their reliable underwater data transmission using digital signal processing modulation techniques, have historically operated over a 5 kHz bandwidth with bit rates up to 2400 bits per second. With the new BlueStreamX2 enhancement, the bandwidth has been expanded to 10 kHz, doubling the data rate to 4800 bits per second.This breakthrough is made possible by the innovative
