For the Su-35 fighter, the fight against air targets is the top priority. As part of the aircraft’s KBO, the Irbis-E RLSU is intended to:
Provide all-weather search, detection, and stable tracking (from any aspect) of air targets in volume and against ground/sea backgrounds, on head-on and tail-chase courses, under active EW;
Measure and output to the aircraft’s information-management system (IUS) the coordinates of air targets and, in special modes, classification features;
Detect and track up to 30 air targets while maintaining continuous volume search (track-while-scan);
Provide discrete-continuous tracking of up to 8 of those TWS targets with update rate and accuracy sufficient for employing AAMs with ARH and SARH;
Provide illumination and command transmission against two tracked targets while simultaneously guiding two SARH missiles;
Provide mid-course correction when simultaneously employing up to eight ARH missiles against eight different targets while maintaining airspace search;
Detect and track helicopters (including hover);
Resolve groups in angle and range (in special modes), forming the “group target” attribute;
Automatically classify targets in special modes (large/medium/small; airplane, helicopter, AAM, CM, TBM, etc.);
Recognize target type (up to 20 aircraft types, foreign and Russian) to optimize weapon selection;
Detect and bear up to 10 jamming aircraft, computing the range to one of them for attack;
Automatically/manually transfer to track a target in a specified zone (including a visually seen target) in close-in maneuvering combat:
“Vertical” mode within 5×60°, and HUD (collimator) mode within 30×20°, at ranges up to 10 km in ≤1 s (tracking in close-in combat imposes no limits on aircraft maneuvering);
(With IUS interaction) prepare AAM launches and support missiles to target:
1–2 medium-range SARH AAMs via correction/illumination channels, or
up to eight medium-range ARH AAMs (or up to four long-range ARH AAMs) through to seeker lock.
“Irbis-E” is intended to detect and track incoming AAMs and SAMs at ranges guaranteeing effective counter-maneuver (no less than 6 seconds before arrival).
That may be a thing that can be update with time. After radar get more info. I remember reading something like that. But i don’t remember if what for IRBIS or for that thing called bos/bosse or something like that. That the Su-35s have.
And you are only taking IRBIS itself into consideration here. Su-35S also has IRST with pretty cracked detection range and we don’t really know the technical details behind wingroot L-band radars, but L-band isn’t affected by RAM coating nearly as much as X-band.
This is extremely irrelevant argument. Not only military and consumer electronics belong to completely different markets, but also you are trying to use an end product on an international market as a basis for your comparison.
every time F-22 changes the aspect it’s RCS will change dynamically and detection range of IRBIS will increase.
Another thing, as i said above is L-ban radars in the slats. RAM coating is not great against decimeter wave frequencies.
Ahem, unless you know the composition of the RAM (not all of the stuff is equal, plus different types are geared towards different spectrums) - you can’t really state that X or Y radar is better at countering it.
Ever notice the differences in shading, colour, etc on a Stealth Jet as seen from different angles? That’s because the material will actually be changed in makeup depending on where on the airframe it is. Even thicknesses can vary.
Anyone interested might find this book worth reading. It covers both Northrop and Lockheed and the different approaches they took.
It isn’t necessarily just the hardware but also the expertise of dedicated crews. The USN has obviously felt that a dedicated SEAD platform/crew is worth it otherwise the F/A-18G Growler wouldn’t be a thing. Have one or two airframes in a strike dedicated to doing the spooky stuff and that allows the other aircraft to focus on their own tasks (A2A, A2G, Recce, etc.)
It’s not about X or Y radar, it’s about wavelengths. Vast majority of modern radar equipment works on X-band so RAM is mostly tuned to absorb this range of frequencies.
Again, there is no public data as to what wavelengths stealth coatings are optimised for. What I can say with some certainty is that the whole - ‘Low frequency/Long Wavelength counters stealth’ claim is usually made by arms manufacturers to sell their Low Frequency/Long Wavelength radar systems.
There is no silver bullet to achieve or negate stealth. Given that such radars have been around in air defence systems for the past few decades - it is unlikely to be an area of the spectrum that everyone but Sukhoi forgot about.
Coming back onto topic - I don’t doubt that the Su-35 is probably the best fighter in the VKS arsenal. Better even than the Su-57, since at least the Flanker family has a well-proven design, produced in numbers with most of the kinks and bugs ironed out.
As to whether it could go head to head with a Western equivalent on an equal footing BVR? I don’t know.
