Should LPI be added to the game for modern radar systems? If so, how complex should the implementation for them be? Should it be simulated like this https://www.youtube.com/watch?v=JP3eI8_BquE, or just simulated as a much faster scan/refresh rate like the upcoming PESA radar on the Su-34?

We alredy have a bunch of PESA, and one AESA (that was designed to be a “silent radar”). They ping like normal.
as the simulation shows AESA and PESA radars should still show up on any semi modern RWR
which they currently do
Yes but all of those are ground radars that were added well before aircraft radars got to that tech level, and AFAIK the PESA coming on the Su-34 is going to have new features that have not yet been seen on any radar in game.
but for the reciving end they are the same

I haven’t seen much if any simulation of AESA/PESA radars interacting with RWRs, do you have a link of ones that show this is the case?
What do you mean?
an RWR is just a directional Radio wave reciver
the only thing that limits it’s ability to recive radar signals is the Band it supports
and any semi modern RWR will receive the bands used by the currently in game AESA and PESA radars plus the majority of what future AESA/PESA radars have
the only thing this LPI as shown in your video does is confuse the distance to the radar that is tracking you, your RWR will still and during the entire time know that you are infact being tracked and from what direction
I cannot show you Up to date proof because it is, as most things are for moden aircraft, fully classified

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
