Chinese researchers claim to have developed a novel coating device that could help submarines dodge sophisticated enemy sonar by resembling water.
Submarines around the world, including nuclear subs, have been playing hide-and-seek with the newest anti-submarine warfare capabilities for years. The advancement in technology has given way to the development of cutting-edge tools that would help navies locate hostile submarines.
The development of the latest Chinese technology appears to reverse that and escape unscathed. In order to locate hostile submarines, active sonar is used whereby the submarine transmits a sound pulse and calculates the time it takes to reach the target and be reflected back.
According to Chinese researchers, the tile-shaped device developed by them can analyze an enemy’s sonar frequency and produce opposing sound waves so that the sonar operator will mistake the submarine for water, Hong Kong-based South China Morning Post reported.
The Beijing Institute of Technology team claims that the low-frequency noises produced by the tiles have an intensity of up to 147 decibels, which is louder than a rock concert and strong enough to block out some of the most potent active sonars used by the US military or its allies.
