By marketing cherry picked vanilla figures that overshadows relevant data. There’s no doubt that Irbis-E has good performance and is the most capable radar on a Russian Fighter but it isn’t so much “powerful” for a modern Fighter radar.
Sukhoi loves to portray Irbis-E having 350 km detection range against 3 m^2 target, which looks quite nice but what many don’t realise is that this figure is for a cued-search in a tiny FoV (10°x10°). What’s rarely stated is that in (normal) volume search that range shrinks down to 200 km. From UAC,
Fucking Quora link a blog post than from some joe and not anything data related about the radar, come on bro lol. even the F-22 can gain 1m2 at 400kms only because it uses a 2 degree by degree radar beam tell me something i dont know already.
We also see this in Irbis-E’s flight test video where it allegedly detected a single target from 268 km but wasn’t able to get a track until 100 km – all the while having just a single target to track.

press control F search 100 on that brochure dont see anything about this range, are you perhaps just quoting this off someone that hates the aircraft? Anyone can make up BS but its more embarrassing that someone points out where is the info and not being able to provide it in return
This shows how unrealistic is the 350 km detection range figure in real combat. It’s analogous to Northrop marketing F-35’s radar having 1,300 km range because it can track ballistic missiles in cued-search from DAS.

1st of all that is not radar but infrared detection lol, the radar data of the F-35 was already given by billy flyn which he states his radar can spot an aircraft from 200 miles away. Even the F-16.net bros already explained that the range was off a rocket

DAS track = Magenta circle. APG-81 track = Yellow
Synthetic Aperture Radar (SAR) resolution is a reliable indicator of performance and level of technology – it’s proportional to a radar’s bandwidth, which in turn is related to jamming-resistance (ECCMs) and LPI. According to the manufacturer, the Irbis-E has a SAR resolution of 3 meter – which is comparable to F-15E’s APG-70 radar from 1980s.
also it can pull a .01 meter resolution at 90kms on radar the range on the apg-70 is alot smaller.
It was great 30 years ago, not by today’s standards. Today a PESA radar with limited bandwidth is vulnerable to modern EW suites – putting Su-35 at a serious disadvantage.
And it’s worse for surface targets, Irbis-E has 100 km targeting range against Naval Destroyers and 200 km engagement against aircraft carriers. This is not powerful by any metric when you’ve F-16’s APG-83 radar having 160 nmi (300 km) range just for creating high-resolution SAR maps.[3]
The Su-35’s Irbis-E might be the most powerful radar on Russian Fighters but it’s not exceptional outside Russia. The over-hyped vanilla figures look great until you realize how irrelevant they are in real world.
Even smaller AESA radars on most Western aircraft will have better performance, especially in a jamming environment. There’s a reason why Russia is trying to field AESA radars in Mig-35 and Su-57. Though Zhuk-AM on Mig-35 won’t complete testing until 2021 at the earliest.[4] Put propaganda aside, and you’ve the mighty Su-35 & Irbis-E showing just how far behind Russia lags in avionics.
350km for 3m2 and 400kms for 1m2 is only achieved at narrow radar beam searches and the F-22 radar replacement was far later than the Su-35. But they are moving onto to photonic radars and the west has not made any advancements than this here.

But of course they are doing everything drone wise even for air to air capabilities.
