your words was which was an answer to

So I got the impression that you were talking about aircraft being spotted when sitting inside hanger.

SAR can spot aircraft after they have moved by spotting the changes in temperature on the ground under the aircraft compared to those around it. I remember seeing an image of an AFB with SAR in a programme while it was pretty easy to tell what planes used to park there from the heat shadow.

However, they only works if the plane had been parked there for some time, long enough for a detectable heat different to form and give enough resolution to ID an aircraft.

If you taxi straight to a shelter after landing, unless enemy SAR was overhead at that precise time, they will not be able to use this method to ID your aircraft.

The latest issue of ordnance industry science and tech told that there are more than 50 J-20 has already produced by CAC, and China will ultimately produce 200 to 300 J-20B that entered production this year.

Could some fluent Chinese members translate the other key points of this article. There looks to be quite a bit of content here and my Chinese is rudimentary .

200-300 this year? Sounds like BS. How reputable is this magazine?

This means China will ultimately produce 200 to 300 of the J-20B series that entered production this year, not produce 200 to 300 in a year (which would be impossible). I edited the translation of 52051 to make it more clearer.

so J-20B is with WS-15 engine ? 200- 300 is very reasonable, but probably not in one year, more likely 5 years

see the comments .. interesting
