The thing is, no aircraft gets developed in Russia without the airframe going by TsAGI for aerodynamic tests and trials first.
I am sure they got extensive test data from that.

“for example, take ground-based radar. Today, this radar is the size of a multi-story home, but using microwave photonics, the station can be installed on a standard KAMAZ truck. The effectiveness and range of the radar would be exactly the same, namely thousands of kilometers. Several of these mobile and small radar systems can be networked, which will only increase their characteristics.”

"The detection distance is very far, the energy conversion efficiency is up to 60%, the traditional radar is only 30%, and the noise is more than 100 times lower than the traditional radar, greatly improving the signal-to-noise ratio, for stealth target theory detection distance of more than 500 kilometers!"

"Unlike traditional radars, it will not be physically possible to silence ROFAR by traditional means of EW. The dynamic range of the photon crystal is about 200 DB. Modern electronic receiver, for comparison, has a range of 40 - 60 DB, and we modern EW complexes provide a signal to the entrance of the radio receiver - in 70-80 DB relative to its threshold sensitivity. Thus, the device that needs to receive the signal is displayed from a healthy state. Even after the interference in his inside there are still processes that do not allow him to work. But on Earth there is simply no energy source for a signal with a capacity greater than 200 DB, so this logic in the case of ROFAR simply does not work. It can be confused by so-called intellectual opposition, but this is a different story."

Sukhoi I believe, acquired/borrowed heavily from, MiG's research and development of the Skat.

Doesn't look like it, to be honest. For starters, Okhotnik is about 50% larger and - such as the degree of design freedom in a very low-observable flying wing allows - many aspects of the configuration are radically different. Leading and trailing edges on Skat had the same sweep angle, the intake duct was bifurcated rather than serpentine for line of sight blockage and the main landing gear retracted inward (think MiG-21). Apart from the cranked kite planform and carrier ops equipment, Okhotnik arguably has more in common with the X-47B!

I like Sukhoi's intake design better, but considering it could have been available almost 10 years earlier and given MiG a much more sustainable product than minor MiG-29K mods, Skat is a huge missed opportunity. When it was unveiled in 2007, the mock-up was already quite detailed with proper landing gear, control surfaces and working weapons bay doors - by then nEUROn display models still stood on plexi-glass poles! But 5 years on, the latter had flown while Skat went nowhere, a victim of the Russian military's total lack of vision regarding unmanned vehicles at the time which also severely delayed HALE/MALE UAVs.

To jam a radar you just need an emission of stronger signal than the thing you're trying to hide, having 200 dB dynamic range doesn't mean you need a 200 dB jammer.
