SCMP says in its report “China powers up new radar tech to unmask stealth fighters” on September 27, “China’s biggest arms manufacturer has tested a new instrument to detect stealth aircraft, technology that could be a military “game changer” if mounted on a satellite or plane, scientists say.” “Terahertz radars are already capable of finding a concealed weapon in a crowd from hundreds of metres away, and a more powerful version is under development to put on an early warning aircraft or satellite to identify and track military aircraft, including the US’ F-22 and F-35 stealth fighters.”

The device is bulky and heavy to be installed on a satellite or airplane, but efforts are being made to reduce its size and weight.

China has developed some radars to detect stealth warplanes but there is doubt whether the radars really work. Experts are sure terahertz radars can do the job but it takes time to develop usable devices.
