China's ‘telepathy' radio could make combat units invisible for electronic warfare edge
Since they debuted in World War I, military radios have played a vital role in sending strategic messages via electromagnetic waves, but it has always been a deadly game of hide-and-seek. The devices present a dilemma: crucial communication at the risk of simultaneously broadcasting the location of their users to adversaries, exposing forces to interception, jamming and missile strikes. But the cat-and-mouse game may soon be over. Chinese researchers have claimed a breakthrough that enables high-speed battlefield communication while ensuring the units sending signals remain in absolute radio silence. One expert, who described the communication technology as 'telepathy', said it could potentially make People's Liberation Army combat units invisible in electronic warfare. Led by senior engineer Liu Kaiyu with the Aerospace Information Research Institute, under the Chinese Academy of Sciences, the team detailed the innovation in a paper in the peer-reviewed Journal of Radars on June 24. Liu's team developed a system that allows tanks, warships or aircraft to send vast amounts of data without emitting any active signals.

World first: how Chinese plane radar tracks moving targets without breaking radio silence
Two unassuming Cessna-208 Caravan aircraft flew in formation, separated by hundreds of metres in altitude. One emitted radar signals ; the other, flying lower, remained utterly silent, passively gathering echoes. Far ahead below, three vehicles raced across undulating terrain, dense with vegetation and scattered structures – a scene designed to hide moving targets in a storm of background clutter. Radar screens showed only snowlike noise, as traditional filtering methods struggled. Then, a technological miracle unfolded. On May 12, China's prestigious Journal of Radars unveiled a landmark study led by award-winning radar scientist Li Zhongyu with the University of Electronic Science and Technology of China in Chengdu, Sichuan province. Their innovation – a ' space -time decoupling two-channel clutter cancellation method' – enabled the silent Cessna to detect all three moving vehicles with crystal clarity. As soon as the new tech activated, the screen cleared without a speck of noise, as shown by images in the paper. Detecting moving targets with bistatic airborne radar, has long been a nightmare because of clutter caused by reflections from land, sea or buildings.
