I was thinking it was a more generic term, like what we usually call ACM mode.
Maximus- as GGTharos said, virtually all radars make automatic mode changes. PRF's may change based on closure rates of a target, targets are prioritized and given more scan time based on preset parameters, etc.
In whatever the manufacturer happens to call the "AUTO" mode, this all happens transparently.
APG-66 will automatically switch to ARG mode when a ground attack weapon is selected. IIRC, earlier versions did something like what I mentioned previously. I don't have the TACMAN, so I can't be specific, and I wouldn't do it on this forum anyway.
AESA pretty much does it all at the same time...
The Raptor takes it even further, with EMCON state increasing incrementally as the target gets closer and the threat level increases. All transparent to the pilot, but designed to maintain maximum stealth while gathering as much information as possible, right up to the point where weapons release is imminent. By the time Raptor is at the highest EMCON state and at the lowest stealth level, the pilot has a full EOB and is ready to shoot.
I have a correction to make. I said to MR

"Helmet" and "Boresight" are FCS modes used to cue an IR missile's seeker- it has nothing to do with the radar."

I just want to say that radars also have "boresight modes", which is just a pencil beam aiming straight ahead. So the term applies to both radars and IR Missile Targeting functions.
Just thought I should clarify that.
