A groundbreaking radar being developed by Chinese scientists could detect and track F-22 stealth fighter jets using signals from China’s BeiDou navigation satellite system.
Using a simple receiving antenna, the radar is cost-effective, can be deployed almost anywhere on Earth and does not emit signals that might reveal its location.
Plus, if BeiDou is jammed, it can switch frequency bands to use GPS, Europe’s Galileo, or Russia’s GLONASS, ensuring uninterrupted operation.
In a peer-reviewed paper published this month in the Journal of National University of Defence Technology, the project team used an image of an F-22 Raptor, the most advanced stealth fighter jet in the US, to illustrate the radar’s hypothetical target.
Estimated performance data suggests this technology could also be applied to the detection of other stealth aircraft, such as the F-35.
China has a large number of anti-stealth radars along its coastlines and on its warships. But these radars are technologically complex and only affordable to a few powerful countries. In smaller nations such as Yemen, Syria and Lebanon, Western stealth fighter jets can come and go freely, with little concern about getting caught.
