Snip:

China’s Ministry of State Security (MSS) has provided Iran with new technology in an effort to prevent infiltration by US and Israeli intelligence, and to help Tehran defend itself from advanced US and Israeli warplanes in the case of a renewed war, according to a 10 February report by Modern Diplomacy.

This includes supplying Iran with advanced Chinese sensor systems and radars, such as the YLC-8B, capable of tracking stealth aircraft and conducting electronic surveillance.

Defense Security Asia stated that according to one analyst, the “YLC-8B is one of the few radars of its type in the world which can continuously detect and track a Western fifth-generation (stealth) aircraft at long range.”

The YLC-8B was developed by China’s Nanjing Research Institute of Electronics Technology. It uses UHF-band low-frequency surveillance to undermine the effectiveness of radar-absorbent shaping used by advanced US aircraft such as the F-35 warplane and B-2 bomber. The Israeli Air Force (IAF) reportedly has 48 F-35 stealth fighter jets in its fleet.

No. They sent the JY-27A system, which only has a 1m^2 resolution (the B-2 is believed to have a radar signature in of around 0.1-0.75m^2 and the F-35 is closer to 0.01m^2), and is indefective against modern stealth aircraft. The YLC-8B allegedly has a finer resolution and may have intercepted an F-35, but I'm not sure if it had hardpoint-mounted bombs, lumberg lenses, or just within visual range. People who know the capabilities of the these systems aren't talking, and people who don't are, however.

    Not correct understanding of radio physics. This radar signature only X band and close to X band. JY-27A is VHF band. Very different behavior. Stealth shaping do not work at all for VHF (wavelength is more large compare with feature size). RAM do not work. VHF signature will not be small. Resolution mean that can not target but do not have to do with detection object size.

    Purpose of this radar is not target radar.
