Sukhoi Su-57 Felon - Technical details, Analysis and Discussion

Doesn’t mean that it’s the ultimate best technology and will always be better. Smerch on MiG-25 provided better results than anything it could face despite using ancient vacuum tubes. Saying that X is better than Y simply because X uses more advanced technology is extremely flawed logic

Like the 4090 vs 5090.

Only jam resistant against garbage old jammers because it ran a stupid amount of power, and the AWG-10 was a better radar set. Even AN/ASG-18 was far superior.

Byelka does not have an extremely high power output to make up for its shortcomings. The more I learn about this radar the more I wonder what they were thinking

me when i only learn from propaganda sources

11kW peak power and ~1500 first gen TRM on a planar slotted array isn’t good

And you took that from the prototype that was shown

Show me the production radar if it’s so different, the prototype is still going be similar to the final radar in these types of things

nice try CIA.

Then i will remind you that a prototype Irbis had only 50% of production version power output, and prototype Zhuk-A on 154 had only 63% of the TRMs of the current version.

If you can’t provide anything better then 11kW and ~1500 TRM it is.

Not even considering that, it’s inherently inferior to other AESA because it is physically incapable of actually good LPI due to its antenna design

Again, show me any unbiased study

Planar slotted array just has significantly worse wideband performance than Vivaldi array, which is one of the main things LPI uses

this was debunked like ages ago bro

input power =! peak output power

Fair enough, then it’s 12-15kW going off TRM count

it does not depend on trm count… 15+ is a fair assumption tho

8-10 watt per TRM is comparable to other AESA radars. 15kW is the upper end

The calculation is
input power * PAE / Duty cycle = max peak power

exactly it is

input power * ((PAE)/(Duty cycle)(1 - 1/gain)) = peak output power

but the (1 -1/gain) term is usually like 0.99 or 0.999 so it doesnt really matter, it just slightly increases the value calculated from before

Doesn’t this only work for other types of radar, AESA is many individual TRM working together, that’s why you see power for each TRM as a relevant number

nope, this is meant for aesa radars only

PAE is the effeciency of a trm itself

this is well as long as all TRMs are identical

Then what would Su-57 peak power be?

something above 15 and below 20
