What are you talking about? The video I posted shows the RWR being completely unable to detect the scanning or tracking being done by the F-35 Radar because of the way it modulates its radar emissions. The simulated RWR only alerts when a missiles is launched by the F-35.

and that part is theory
the modulation has to be within the Band the Radar can emit, if that band is within the range of the RWR then it will detect it, unless it’s the RWR on an F-35 or F-22 in which case it will filter it out
but that doesn’t apply to any other RWR because the terrible oversight to filter out signals within it’s range is patented
Theory is all we have to go off for modern radar systems though.
But doesn’t the RWR need to have certain filters in place for signal strength and signal repetition so its not constantly polluted with background RF signals? Isn’t that what LPI systems are designed to exploit?

They will probably search like normal, that’s how they are currently. The new Mi-8 has a AESA and searches like a normal one
the bands used for radar are reserved for it too
nobody else is allowed to send on theye frequencies, and if they do they’ll get a quick visit from the local radio agency
because of this it was never needed to filter out signal strengths as it is only an advantage if you can detect a hostile radar when it’s so low strength that it can’t detect you yet

Well I have no idea if there are any natural sources of radio noise in the 1 - 30 GHz range, but don’t AESA radars have the capability to emit many multiple different Frequency and PRF signals at a single target in a seemingly random sequence that is known only to the radar that sent them, making it nigh impossible for an RWR to determine that it is being illuminated by a single emitter source, unless the RWR knows what kind of randomization a given radar will be using?

They can jump frequency within the band. There is a reason why a AESA radar is stated to be for example X band. Many other radar, even not ESA can do so, but its not as fast as AESA.
Can non ESA radars be LPI?
They can modulate their frequency, but it takes much more time and is less effective compared to ESA.
it would show up as multiple different unknown radars on the RWR
the software behind your cool modeen radar can’t figure out that you’re being tracked but it surely can figure out that theres some source aiming for you
All current radars (including PESA/AESA from Firebirds update) is just a placeholders.
It have nothing similar with IRL radars, radiowaves and how it really works.
So till Gaijin finish their radilocation homework - all speculation about radars is nothing but just empty words.

I fully doubt anyone here would actually be able to play the game on their systems if the radars used an accurate simulation instead of what we currently have
We even have an mechanical radar with LPI(IRL) - longbow

Would it still show up on RWR if it was a ton of different emissions of different strengths all hitting simultaneously?
Yes. The Tornado F.3 had an LPI mode Gaijin haven’t modelled.
Curious how low the PI is on a single emitter radar. I think if anything like this is added to the game it should come only in the form of LPI for search only, LPI with tracking or guiding missiles would likely be bad for gameplay.
yes
if I throw 20 different sized balls at you would you notice that?
No
RWRs do not trigger on every pulse they receive, otherwise they would have an incredibly high false alarm rate from triggering on background noise all the time. An RWR typically needs to receive multiple before it triggers an alert in order to tell that it was not just random background noise. If you have a radar which is constantly changing frequency, using low transmit power, and a complex scan pattern it becomes very hard for the RWR to work out what is random noise and what is a radar.
But we don’t need to speculate. We have a report from trials of the Tornado F.3’s LPI mode and it confirms LPI radar modes are indeed effective:
During trials the low probability of intercept (LPI) characteristics of AI24 when radar CX0 (FA mode) was selected became very apparent, very low detection ranges were achieved even with the high sensitivity of this receiver, implying that the probability of detection in search by a less sensitive receiver system is low

Depends on the environment, If I am getting constantly pelted with randomly sized balls with random force, but they all kinda fall within a specific threshold of size and force, I may or may not notice if a few of those balls are slightly larger or hit slighter harder, but I will definitely notice if a single huge ball hits me really fucking hard.
