Chinese scientists have made a breakthrough in submarine detection by creating a radio-emitting source in the sky using high-energy microwave synthesis technology.
This virtual signal source, which can be called a ghost radar, can emit electromagnetic waves continuously while traveling at nearly the speed of light.
The scientists made this claim in a study published on November 25 in the Chinese academic journal Modern Radar.
The extremely low-frequency (ELF) electromagnetic waves, capable of penetrating seawater, enable the detection of submarines hidden hundreds of meters below the surface.
According to the research team led by Li Daojing at the National Key Laboratory of Microwave Imaging of the Chinese Academy of Sciences, this breakthrough is a “disruptive technology,” the South China Morning Post writes.
