ok thinking of that ive have a idea upon you could detect the f22. as we know there is signal noise from the sun. this noise get under the f22. or better said in the back under the f22. then theyre reflect by air exacly into the f22 from wich theyre reflect to the far front of f22 where a passive radar waits and upon the angle they enter they create a specific phase shift signal in the circuit now all you have to do is to corelate continuous phases shift with the continous angles at wich the f22 reflect the waves as he approach target so here we are f22 is visible
look what the thing that i've said is very simple : we have waves reflected from f22 at angles now as far ive read any electromagnetic wave when is not see (by eye in visible waves or antenna in case of radio waves) at 90 angles the signal is less powerfull (think that your eyes cant see better to the sides than the center) so in case of f22 (because this is where i want to reach) you just need a radar that follows those bunches of low signal waves also think that if the plane would be in consecutive movement the waves will cause consecutive levels of signals so here we are

Nonetheless the theoritical groundwork of it (The paper also include mathematical equation for predicting performance) Showed that it might not be promising. Nonetheless it is one hell of interesting concept.
I was thinking something like Russia using ground based EW systems to target hostile F-22, F 35 etc over Russian airspace if they are involved in a dogfight with Russian Su 30 or Su 35s.
But then I suspect that ground based EW systems will also affect the Su 30s and Su 35s adversely.
first of all i've been talking about a passive radar who doesnt send anything just receive. then yes ofcourse i know what is the shape of f22 and why is used for. third you could have a idea how far is it by having two (at least) radars close on each other and triangulate the signal ofcourse the signal bouncing from aicraft is the same in terms of frecvency with many waves in the air but has another angle at which is reflected by plane and as far as i understanded every wave that doesnt hit a antenna at 90 angle produce a phase shift let me search on this on internet

Maneuverability is NOT the holly grail in aerial combat. The T-50 is pale in comparison to the F-35 especially in stealth and situational awareness which is of number one importance in any fighter aircraft. Could this be true????

It was supposed that sensor fusion would be an arena where Sukhoi would find it rather difficult to come up with a relavant mature solution. With the introduction of IMA BK mission computer and fire control complex developed in house, the critics may have been silenced. There is still some time to go. And the rear fuselage shaping will be refined, those cylindrical unstealthy nacelles will give way to faceted ones once Izdeliye 30 appears. then the rear and beam signatures will be as good as the F-35 if not better. Hope the prototypes coming out would carry these features.. expecting replays dear admins,,

DIRCMs should deal with all optically guided missiles like ASRAAM and AIM-9X etc.
This suggests it will turn into a gun fight.
Who was saying that manouverability wont be important... ohh that is right... the people with the less manouverable aircraft F-35 and F-22...
Why don't I believe them?
