But the FIM-92 still uses a single IR detector as illustrated in that diagram?
It wasn’t until dual band IR detectors (a relatively recent development) that a single FPA could detect more than one waveband.
In the meantime I will read the patent you have linked.
Edit: Its a IR + UV seeker with two separate detectors, not a IR + IR seeker which is what I originally discussed:
Fair point
It’s also possible that each row scans a different band tbf (so one 128x1 for one band and one 128x1 for the other) but that we simply don’t know (and prolly never will). Maybe the Block 2 will bring more clarity once we know more about it’s new seeker.
That’s literally the IR/UV POST seeker that the FIM-92B, later Stinger variants (and other missiles like the MIM-72G, and prototype XRIM-116) use, US4009393
The point was that that the POST seeker’s arrangement is an example of a notional optical train that could allow for a two discrete detectors to be used, regardless of which bands the detectors are actually optimized for.
The reason it uses UV and IR (in place of MWIR/SWIR for example) is that it magnifies the work required to generate an active formulation that can suitably defeat both detectors simultaneously.
What you are referring to is a dual band IR detector which provides independent sensing of different spectral bands within individual pixels. This is a visual representation:
The two leaders in this technology are the USA and France. As for France, the technology didn’t mature enough for production until 2009/2010 (or so). IRIS-T entered service in 2005 according to Wikipedia (please correct me if I’m wrong), so it’s very unlikely IRIS-T uses a dual band IR seeker.
This just flagrantly ignores the differences in terms of SWaP between an IR and UV detector. An IR seeker with two separate detectors is possible but this would most certainly require staring arrays as opposed to linear arrays which use scanning mechanisms (such as on IRIS-T).
'05 seems about right. It started development in the 90s, if france didn’t have a mature seeker till '09 then it is very unlikely that IRIS-T had one already. (Unless Diehl just kept quiet about for some reason, also very unlikely)
From what i searched dual color seekers see from 3 to 5 and 8 to 13.
Excerpts:
“Such seekers, which are most sensitive to the 3 to 5 micrometre range, are now called single-color seekers.”
"This led to new seekers sensitive to both the exhaust as well as the longer 8 to 13 micrometer wavelength range.’
“Modern seekers combine several detectors and are called two-color systems.”
Which i take to mean that the IRIS-T has a dual band seeker.
Unless you guys are talking about something else.
Holy Racism man (They are the nation the the Meteor propulsion design comes from)
Can you provide a link to your source?
I like lurking in this thread here there is always a ~95% chance that either the UK or Germany (tho pretty much anyone has a good chance) will be described in less than favourable terms than France simply because they didn’t focus on X or Y thing at a Z time (but if you dare bring up the times when France has been less advanced than them or still is, you will be swarmed because muh national pride simply cannot accept that lmao).
/h
A dual colour seeker can be achieved by two separate IR detectors each sensing a separate wavelength (LWIR and MWIR) or a single IR detector sensing two wavelengths (known as a dual band detector).
The issue with using two IR detectors is that it takes up much more size and weight. IRIS-T uses a scanning mechanism which takes up even more size and weight, it is therefore unlikely it uses a two detectors due to SWaP constraints. Unless explicitly stated, I simply doubt IRIS-T uses a dual colour seeker.
When is Germany indigenously developing their own plane? Or are they still leeching off (when they are not undermining) the UK and Italy, and now France with SCAF? xD
Theres this article from 2000 sourced from Flight International: 1
That states the IRIS-T and Mica actually have similar systems: “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. Matra BAe Dynamics uses a similar system on the IR-guided version of its medium-range Mica missile”
Some other new bug reports regarding the missing armaments on the Rafale
Rafale missing 6 x Mk81 payload // Gaijin.net // Issues
Rafale missing 6 x Mk82 payload // Gaijin.net // Issues
Rafale missing 4 x Mk83 payload // Gaijin.net // Issues
Rafale missing 4 x Gbu-16 payload // Gaijin.net // Issues
Is that why Dassault wants all of our secrets but refuses to share theirs? :P
All threads would be better without hostility.
Also isnt france codeveloping a tank with germany?
He’s just trying to bait ppl into being toxic in a thread where he has backup from other french mains as to his presumed total superiority of french technology. Its better just not to engage with that type of person, and this convo is skewing off topic anyways, should be directed to either the German EFT thread, or the Fox 2 thread.
Yep, the MGCS program
lol
