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
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.
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 .
@DirectSupport The current reported range for DDM NG is 27km against a supersonic missile with a skin temperature of 250 - 300°C. With these new changes, it will be important to see if the skin temperature of various missiles can be measured. It might be possible to increase the detection range even further for DDM NG.
It’s pretty great we have that baseline already of 27km at 250-300 celsius for a supersonic missile, I would imagine for something like AIM-54, a longer range could be achieved.
Yes. It will provide the Rafale with an exceptional degree of situational awareness. The baseline range of 27km would appear to already be able to detect a threat such as IRIS-T on launch, providing a lot of time to deploy countermeasures and evade the threat.
DDM NG should also fare pretty well with atmospheric transmittance as well. But I doubt the devs will model that lest they completely nerf PIRATE IRST.
