Will get to the USA: A new technology for the underwater war has been developed in China
Earlier, the "two -pass" acoustic environment of the Beaufort sea - the layered structure of aquatic masses with contrasting temperatures and salinity - was a problem for hydroacoustic systems. However, China has found a way to adapt to the difficult conditions of the Arctic. Having analyzed the data of recent studies by Arctic China, the team found that low -frequency sound waves can be transmitted between the ocean layers depending on their frequency.
By tracking these sound waves and measuring their strength at different depths, scientists can determine the depth of the target at 600 Hz. "This possibility of acoustic capture opens up new opportunities for long -distance, navigation and active/passive detection systems," scientists said. This method also allows to filter the environment, providing accurate tracking using only six arrays of sensors, which is a critical advantage in ice, stormy waters.
In this case, the technology has some limitations, for example, accuracy drops sharply when the frequency of the sound source drops below 300 Hz. According to scientists, hydrophones should be located in both channels - on the surface and in the layers of bent - and improper placement distorts the testimony. Earlier, the largest Chinese weapon manufacturer Norinco has introduced Bullet Curtain air defense system capable of destroying rockets and switches.
