I do not know, I did not do the calculations for the Su-57

PIRATE can range fully accurately using kinematic ranging, its a state of the art IRST and cost as much as the radar did to develop. There is a reason LEGION and IRST 21 utilise the same tech. We know CAPTOR-M can range to within 10 metres, PIRATE is described as having equal accuracy in range and better in angular resolution than the radar.
Pirate can also guide missiles all the way with 2-way datalink.
the reason legion and irst21 use the same tech is that legion is literally just an irst21 put in a pod

its a radar, so yes
just not possible without laser ranging. it compares visual/IR signature, size, angle etc with models stored in its data and then calculates a rough range to target
how rough exactly im not sure, but its not as accurate as a radar unless the actual range to target is like… visual
under ideal conditions it might but this wouldnt be that hard to mess with
yep, i think you can mess up its ranging with multi-spectral flares

i have heard the F-35 new sensor has this capability too, to accurately range through triangulation
might be harder to counter comaped to a fixed database
this is basically visual identification and size matching with the dimensions of the target aircraft stored in the data
basically theyre the same, triangulation is the method used, the database is the data
i have heard it can use datalink to do this too, with more than 1 F-35 looking at the tagret then it would be more accurate in triangulation no?

i think the F-35 has LRF no?
and yes with two F-35s, it will basically give a precise location to target (WRT GPS even)

They reuse the same tech as PIRATE. That was my point.
Unequivocally false, it just requires a lot of software, PIRATE has a virtually instantaneous refresh rate and rapidly compares the micro differences in UV and IR signature to obtain a range.
Pirate was initially software limited to 70km due to this but thats since been lifted.
PIRATE uses software to ignore things that do not exhibit ‘aircraft like characteristics’ and does not display them it is also essentially IIR. A flare like BOL which is Pyrophoric would block tbe sensor, but it would still be able to track the range of said flare if it couldn’t see through it which is what BOL does.
I’d be happy to link you some reports to the operating systems of PIRATE when i get home.
well yeah i get they use the same concept but its not the exact same tech
exactly but theres only so much air UV or IR radiation can go thru before its too weak to detect
but if you block the FOV or the targets IR/UV silhouette, you effectively go behind hard cover and mess up the range of target

and what happens if you just go from AB to regular mil power back and forth to screw the sensor up?
the aircraft chassis doesnt change in size so, AB → mil wont rlly do much
but doesnt it use the IR signature? if you switch between the two itll affect the signature consdierably
the fuselage itself also gives off a pretty substantial IR signature, which is why IRST can track it even if the engine turns off
well yeah, but shouldnt the change in IR signature from AB confuse the sensor?
not really, the fuselage dimensions are saved in the database, the AB jet flame isnt rlly going to change that aside from act like a torch on the IR spectrum
so detection range will be increased but range to target wont rlly be changing
ah ok.
to get back on topic, in report on F-22 EW suite, it was stated that if the enemy wasnt careful in their use of radar, the RWR on F-22 could provide enough information for an AMRAAM launch.
luckily for us, “not careful in their use of radar” is most of the WT playerbase
