One ylc 18 was capture by the al nustra during the syrian civil war .likely the radar already in us cia lab.
There was an anti-stealth radar sent to Syria for testing against US F-22 and Israeli F-35 around the area. It was destroyed by US forces. It was not captured. It surely would have numerous self destruct mechanisms and bombs in case of capture. Unless there was another anti-stealth radar sent to Syria, I think you are confused.
People were quick to say that the anti-stealth radar didn't work... but such is the intelligence of the average human... because anti-stealth radars that are effective at detecting stealth fighters at range are also able to create forcefields to protect themselves from said stealth fighters... NOT.
The radar was sent so that Chinese engineers could evaluate its performance against US stealth platforms. It wasn't sent to participate in air defence. It was not hooked up to any air defences or missiles, just there to gather data on detection resolution and range against F-22s flying around Syria (yes F-22s were used hence why the Chinese sent one anti-stealth radar unit over to take advantage of a once in a lifetime chance to test anti-stealth radar against adversary stealth fighter).
