Researchers at Jane’s (IHS Markit) have identified a JY-27A . VHF radars, with their longer wavelengths, are more likely to detect stealth aircraft.
Phased-array radars, unlike traditional “dish” radars, are flat panels composed of hundreds of smaller transmit/receive panels. While traditional radars are like turning on a flashlight in a dark room—everyone can see where the beam of light is coming from—phased array radars are more difficult to detect. They’re also less susceptible to jamming.
“There are unverified claims that the radar can pick up hostile stealth fighters at ranges of up to 500km (310 miles.)”
