Chinese Scientists Develop 6G Technology for Submarine Detection
Chinese scientists from the National University of Defence Technology have made significant advancements in 6G technology for the detection of submarines. Their work, published in the Journal of Radars, explores the use of terahertz technology in underwater vessel detection and communication.
Terahertz technology operates in a frequency range between microwaves and infrared radiation and has the potential to achieve high data rates and low latency. It carries more information than existing communication methods and can collect data about the environment. Some Chinese airports already use terahertz screening devices to detect hidden items on passengers.
Thanks to increased investment in 6G technology, scientists have developed breakthroughs that make mass application of terahertz technology possible. The team suggests that the terahertz submarine detector could be compact enough to mount on a drone. This offers advantages such as mobility, low cost, and flexible deployment.
The technology can complement existing submarine detection methods such as magnetic anomaly detectors (MAD), microwave radar, or laser. It provides important information for the detection and identification of submarines.
The Chinese scientists conducted experiments off the northeastern city of Dalian in the Yellow Sea. They used an artificial sound source to simulate submarine noise and carried the submarine detector on a research ship’s extended arm to mimic drone flight. The terahertz sensor successfully picked up man-made ripples on the water surface, even in challenging sea conditions.
The high frequency of terahertz waves enables ultra-sensitivity, and the scientists have developed an algorithm to effectively identify nanometer-size ripples over wobbling ocean waves. This technology could also be used for submarine communication, allowing for covert coordination with friendly aircraft during military operations.
The results of the sea test indicate that terahertz technology has high signal resolution for cross-medium communication, which is a challenge for naval powers. Previous experiments have shown successful communication between water and air using 6G technology.
This breakthrough in 6G technology holds significant potential for underwater vessel detection and communication, offering new possibilities for submarine surveillance and covert operations.
