One of DAS's lesser known features is that it's capable of 360 degree IRST of hostile aircraft, with weapons cueing. See reference HERE
That is one of the most recent mentions I can find about this capability of DAS. It's almost never talked about these days. I suspect because it's quite effective.
From what I've been able to glean from the internet, DAS's target hunting functionality goes something like this.
1. DAS sensors around the aircraft track IR sources relatively roughly, closely enough to slew the EOTS onto them but not closely enough for tracking/cueing.
2. The EOTS systematically slews between all the IR sources the DAS sensors pick up. It uses its high zoom and laser rangefinder to both detect the range of the target, and also attempt to guess its aspect and type (and therefore hostility) using AI and the onboard target database.
3. EOTS categorises the threats based on the threat posed to the aircraft, and prioritizes the highest threat ones.
4. High priority threats are scanned by the EOTS more often than lower priority ones, providing more accurate tracks (and by knowing where you are, and the bearing, range of the target aircraft, and the change between multiple scans, you can calculate target speed, heading and position)
5. This information is passed to weapons in much the same way as TWS, and updated via datalink as the missile is in flight. Go here, fire up your seeker head, kill the thing.
6. This operates even if the radar is switched off, helping the F-35 maintain stealth, but the EOTS can classify radar tracks too.
So, will the DCS F-35 be able to switch the radar off and go hunting MIGs? Because I think with this capability, it will be rather ridiculous.
