Arguably legacy IRST still exist, even if victim of production obsolescence. Not sure it can be installed along side the latest FSO though.
AF / DGA selected to not rush on the IRST replacement awaiting some of latest tech to mature I beleive. Meanwhile they rely ,apparently to their satisfaction, on MICA IR seekers and DDM-NG and eventual reco pod for IR watch.
You can look on two different direction at the same time, you can't do that with a single IRST.
How fast does it scan relative to a normal IRST though? The IRST scan rate kind of wipes out that advantage. Then you've got the fact that IRST will have already scanned that area a million times before any target gets within range of either missile seeker.

Are there any particular details known about how the MICA IR is actually integrated in the sensor fusion process? I suppose it has at least two FoVs, one for search and one for acquisition? Does it possess a multiple target detection and tracking capability or is it simply searching for and acquiring the first target it detects? Are the bearing data produced by its seeker fused to increase angle tracking accuracy and/or can other sensors, the radar in particular be primed with it or is it more of a "slave to target" mode where the IR seeker itself is slaved to another sensor track?
Concerning DDM-NG is there more known about its actual capability to do something else than plain missile detection and warning?
Thanks to the high-quality IR imagery produced by the DDM-NG sensor, many other applications can be foreseen on aircraft (Air Policing, Situational Awareness, Targeting, Assistance to navigation, Air Patrol, Anti-collision, “IR Black-Box”,...). DDM-NG can also be installed on wide-bodied aircraft, helicopters or ground vehicles."
The question is whether any of these potential capabilities have been implemented already?

IRST is a good thing to have (that's why Rafale have it btw) but like Xman said due to production obsolescence many Rafale don't fly with it and rely on Mica and DDM-NG.
FAF don't have the budget of the USA thus they need to prioritize some upgrade and they chose to upgrade the TV channel of the FSO, the DDM and the Damocles pod and postpone the IRST channel for later upgrade and rely on Mica, DDM-NG and new Talios pod.
If you compare with the Typhoon (i know you love it), he has a good IRST but no AESA, FAF chose to prioritize the contrary.
Except DDM-NG doesn't do IRST according to its manufacturer. PIRATE was never prioritised it was just always there because they thought radar range may be compromised in a cold war scenario.
It hinges on the computing power of the MDPU to process data from the RBE2-AESA radar, the “Front Sector Optronic” (FSO) system, the SPECTRA EW system, the IFF, the MICA infrared seekers, and the data link.
Autonomous lock-on from the seeker’s own IRST scans(from MDBA brochure)
La version IR fait également office de capteur de veille infrarouge ce qui permet notamment à l’avion porteur de détecter des attaques de missiles infrarouges. Le MICA dispose par ailleurs d’une capacité multicibles interne qui permet au pilote de traiter un groupe de cibles proches.
In English. The mica ir version is also used as IR watch notably for detection of IR missile threats. The mica has an internal multi target capability for treating a group of targets.
On the subject of fuses, I note the MICA has an RF proximity fuse, now I noticed something in a Russian EW advert that suggested their EW can play with RF fuses causing premature or delayed detonation. See 3:04:ASRAAM accepts target information via the aircraft sensors, such as the
radar or helmet mounted sight but can also act as an autonomous
infrared search and track system.
Lukos, what is your point here ?
MICA IR is also employed as IRST on 2000-5. Scan pattern is optimized by the aircraft's attack & navigation system which takes into account the fuselage and fuel tank position.

The capabilities of DDM-NG are therfore implemented depending on spectra upgrades.
What's the MICA seeker's FoV? I was given to understand that it was around 120 deg (i.e. 60 deg off-boresight).
about "blocked by aircraft", there are two MICAs, one on each wingtip, so, unless you already shot one, chances are that each missile covers pretty nicely what the other doesn't see
The multitarget capability for "treating groups of targets" sounds somewhat like "picking one target out of a group of closely spaced targets. But there is maybe something lost in translation.
Thanks for this one.
Brief and powerless is Man's life; on him and all his race the slow sure doom falls pitiless and dark.
The article indeed talks about laser, EM and IR threat detection and targeting and also about the "visual data feed" from the MICA IR seeker, I suppose this should have been better translated as "bearing data".
"The Rafales work in a truly networked environment, and are fed targeting and other tactical data from a wide range of coalition sources through the Link 16 datalink. Incoming data is combined with that collected by the aircraft’s own sensors – Thales SPECTRA self-protection suite, OSF electro-optics, RBE-2 radar and even the infra-red guided version of MBDA’s MICA air-to-air missile which, as it scans continuously, can provide IR imagery to the central data processing system. “MICA is not just a missile, it’s an extra sensor as well,” says Pierre G., and its detection range is much longer than generally supposed.
About the multi target, I did read at one point the possibility for the missile to optimize detonation for taking out multiple targets at once, but not totally sure how accurate or even pertinent that is.
French team in India to start Rafale negotiations
French team constituted to negotiate the Rafale deal has arrived in India and talks can start anytime now, Defence Minister Manohar Parrikar said today as he described the agreement as "one of the bold initiatives" of the Modi government.
Parrikar said India has constituted a committee headed by Air Marshal SBP Sinha to hold negotiations with the French team.
"The negotiations on Rafale deal can start anytime from now. Indian government has already formed a committee headed by Air Marshal Sinha. The team from France already arrived in India on May 12 to start the negotiations," he told reporters.
Here is a slightly different article he wrote about egyptian sales http://www.defesanet.com.br/ho/notic...-fighter-jet-/
