So they can detect quad copter drones when they know exactly where too look.

Stunning. Literally how the very very very first radar detected an air craft: by it blocking a signal between an emitter and a receiver.
>Thanks to the thousands of Starlink satellites that have been launched by SpaceX so far, scientists are now hoping to use disturbances in the high-frequency radio signals to track stealth aircraft.
Provided they pass directly over your revivers just as a satellited passes over head.
>For now, the team has only tested their method on a drone that flew at relatively low altitudes, and it remains to be seen if Starlink radiation could reveal larger and harder-to-spot targets such as stealth aircraft.
By this method, you can pretty much detect anything that is not transparent to that radio wavelength. But we knew that in about 1935, what you cannot do is detect and track it in anything other than the most random chance of circumstances.

Looking up to the sky also works. Doesn’t mean their missiles can lock on.

Please stop spreading this clickbait bs. It’s already been widely shared that this doesn’t really affect anything.

Not sure if Russian disinformation or Chinese government just lying again.

Can’t we do that with certain long(?) radar frequencies anyway?
Distinction being one can find the existence of a stealth aircraft and vaguely track it but has not enough resolution to create a positive target identification and lock to fire a missile at it?

Weird. This is the kind of stuff you don’t make public.
TL;DR, China was able to detect a non-stealth drone using passive radar.
This doesn’t get them any closer to being able to fire on stealth aircraft.
>As the [*South China Morning Post* reports](https://www.scmp.com/news/china/science/article/3278209/starlink-radiation-makes-stealth-target-glow-chinese-radar), the team used a DJI Phantom 4 Pro drone as a stand-in for such an aircraft for an experiment
