If you want to be fair, the Rafale has sufficient low observable qualities and the Eurofighter does not. So where did those studies from Germany go?

So I decided to read up on the seekers a bit more now that I’m of work.
From the source that @WereCat888 provided:
IRIS-T, meanwhile, uses a two-colour seeker based around a 128 x 2 array which uses a scanning mirror to build a larger picture of its ±90° field of view. […] [BGT IRIS-T marketing manager Gerhard] Dussler says the two rows of 128 elements are offset, creating a so-called “staggered linear array” so that data does not “fall through the gaps” created when the rows are aligned.
Sounds like IRIS-T uses two separate rows of 128x1 detecting different IR-Bands each, not the same pixels detecting two bands.
Also:
How did MICA-IR enter service in 2000 (Source) with a dual-band seeker if that tech wasn’t mature until '09?
If that is true (which is still dubious), it would use two seperate 128x2 detectors.
Mica IR doesn’t use a single dual band IR detector. It uses two seperate 128x128 staring arrays.
Why would it need two separate 128x2 detectors? 128x1 scanned fast enough should be enough to produce as high res image
Same concept as IRIS-T (apparently) uses then.
Because when the size of an array is described (in this case 128x2) it is describing the size of a single, whole array.
Except Mica IR’s seeker doesn’t use scanning mechanisms. If IRIS-T uses two seperate detectors, it would require two seperate scanning mechanisms making it (relatively speaking) extremely bulky and therefore unlikely.
There’s also the case that a bi-spectral seeker has never been claimed by Diehl. It would be very surprising if IRIS-T used such a seeker but was never advertised as such.
Yes, and the marketing director is saying that two rows of the array are separated. Which, combined with the statement that it uses a two-color seeker, suggest each row of that array “sees” different bands. Not that there are two separate arrays.
Have you guys noticed that the ACM mode of the Rafale radar (RBE2 AA) has a particularly slow scanning speed compared to its counterparts, and is also much slower than the search speed of the radar’s BVR mode.
Perhaps we should submit an issue
I will find the original source and get back to you in a more relevant thread.
But at first glance, it seems the “staggered” arrays is used to offset a large pixel pitch not that each array is sensitive to a different waveband.

The MICA seeker has to use scanning mechanisms otherwise it would provide a full picture. To get rid of a scanning mechanism you need a FPA (Focal Planar Array) like the 9X, Asraam and MiCA NG.
Also I would refer to the book Missiles Tactiques, by Carpentier from the COMAERO, page 253 where it is stated “an IR seeker with IR-CCD sensors (two rod arrays for bispectral detection, allowing for a very effective decoy discrimination)”
The MICA and IRIS-T seekers are very similar. They both use two rod arrays of 128 elements (or 64x2 in a checkerboard pattern but that is essentially the same thing), scanned mechanically on one axis, allowing for bispectral imaging infrared.
SAT proposed a 64x2 detector for Mica, but Sofradir was instead selected to develop a new detector which is understood to be a 128x128 staring array.
Scanning mechanisms aren’t required for missile seekers. The current trend is towards smaller physical size, larger format staring arrays.
As for IRIS-T. The source you cited actually states the IR seeker combines two 64x2 arrays:
This is not unheard of and a similar technique was used for the UK’s Stairs C program (which i will attach a source for momentarily).
It also states the seeker has “monospectral detection”.
Edit: Source for Stairs C detector:
@Kir Whilst we are here, the above source in French is published by France’s DGA and states that IRIS-T uses a monospectral (single waveband) seeker.

Little reminder that I’ve a list of all valid Bug Reports in the OP;
I’ll add DirectSupport newest reports soon.

That settles it then, mono-band seeker. Thanks

does anyone here have some docs prooving that the rafale can actualy turn off the AOA limit ? i know it can do it thanks to a video of an old rafale pilot but it’s not enought for gaijin …
also i found this site saying that the rafale can pull 100°AOA and -40kts so i guess it does mean that it’s remove the limitator .

nice .
i really hope it will pass cause if they are not satisfy with that then i guess we will have to do the chad moove AKA leak some secret docs .
