US submarine may have made detectable wakes before South China Sea mishap, study suggests
- Chinese scientists have used real-world data to study submarines’ speed and surface wake, with unexpected results
...
Increasing the submarine’s depth can also reduce surface waves. But in recent years, wake detection technology has made rapid progress. According to a maritime test announced by Chinese scientists in August last year, a new type of anti-submarine radar based on 6G technology
on the undulating sea surface.
On May 20, researchers from China’s Naval University of Engineering published a paper claiming that
technology can help detect submarine wakes in complex sea conditions with 96 per cent accuracy.
But it does not mean that a submarine is always safe at lower speeds. Li’s team found that significant resonance can also occur
when the submarine travels at around two knots, increasing the
