""The Gripen has participated in a number of joint exercises, including Red Flag Alaska.""

 

I did not know . Any link please ? :-)

 

Cheers .

Pfff ... You people are stubborn . Even when we are on the same track , you want me to be wrong .

Please think about the others , they might get tired of your silly attitude , I mean it .

 

We are all talking the same language here regarding the "interferometry" . I explained roughly what it was and how it could be used , then Herald gave us some more details on the subject and for no reasons started to dislike what I 've said (?) .

Then Rufus came like a mad dog , barking at everything with absolute no knowledge on what was going on (?) .

How should I respond to such evident hate ? Simple , I keep my calm and keep posting relevant stuff .

 

Cheers .

The DAS is revolutionary as a threat awareness system.since it uses an electro-optical sensor web to give true 360 degree threat bearing information to a pilot so that all he has to do is look at it instead of fumble for the presentation through a HUD .  

I agree on the DAS, but DAS is not the entire avionics suite and not representive for every single system. The EOTS for example is a Sniper XR based system, the F-135 a redesigned F-119 etc. What I want to say with that is that not all of the systems onboard the F-35 are entirely new and that given the time it will take until the aircraft goes operational with all of that stuff, you might see quite compareable systems onboard existing designs.

  .

And BTW I'm well aware about those public stuff. The point is it was claimed "it is = fact" while it's raw speculation nothing else. I don't say it won't, but also don't say it will if you know/understand what I mean.

Opeval for F-35 is 3 years away. The French will not have their F-3 Rafale before we have our Sparkies IOC the way things are going. In fact 2014 deploy is 5 years away.  

How many? One?

Wingman is uninformed. If you want to support Sampaix, then by all means do so. The YF-23........

 I think you missed the point here.

 

Example. 

 

The stabilizer is primarily there for CONTROL-even in :LO aircraft.. It is not a radar signal return defeating feature. Its a reflector. To mitigate that defect, the stupid things get a dihedral edge shaping and are canted so as to scatter and redirect the refraction angles of signal return  The Squall shows nothing of the kind.of signal return management for shape and cant, so I know that its a signal return bullboard, just by looking at it..

No idea how many exactly, but definitely a couple and not just one.

 

No you will not. The engine for example is quite beyond SBECMAs ability to duplicate. Our IR systems are at best a generation AHEAD of yours. As for radar, the French haven't even figured out how to make an AESA that works without US help. Nor can you..

 

Huh? The entire statement makes no sense in relation to my post. BTW I'm neither french, nor was it related to the french here at all. 

How many? One?

 

No news here at all and you still seem to miss the point. 

BTW at whom is the "go back to ground school" aimed?

 

""Lie: if you knew what you were discussing you would have explained HOW IT WORKS""

 

Oh for cry out loud , I was only explaining the basics and I am correct . Stop it !

""The SU-30MKI uses the N011M Bars PESA radar, which is the most powerful of its kind. It uses the R-77 BVR-AAM, which along with its powerful radar make it it a very formidable ASF.

WVR, the Sukhoi has a HMS and a IRST,and one of the best WVR missiles in the world, the R-73. together they are very deadly.""

 

You know bull when you read it, Steve.

 

In simple English as applied to LIGHT, (this includes radio waves): interferometry is the means whereby  the receiver uses  a pair of comparators separated by a known baseline distance. The receiver points at a single emitting light source at an unknown distance away. The receiver takes the common signal from the target and that signal is split and the split signal is routed through the timed interval setup (the known baseline distance separation of the comaprators). The comparators recombine the signal after thus "maze run" and straight run, and a phase interference pattern is analyzed.That will give you a rough idea of how fast the object moves over time as the phase pattern should time change with aspect presentation and distance (if your clocks are accurate enough) as the sugnal moves across the sky. Since we can build two of these rigs with another kinown baseline and use bearing triangulation to get a very rough range we can very roughly estimate that range. Hence two values, speed and range, give us a very rough track. The problem is that IR crest trough wavelength is too imprecise to generate a firing solution over usable time. The phase smear is just too broad for a good crest count in the few seconds that you have and the range; a "blob" almost a sky second of arc across and with a time distance variant of signal that could be up to 1/50th of a light second makes close range gating useless. 1/50th of a light second bu the way is 5994 kilometers. See the problem?
