Radar modes are things like Area Search, Track While Scan, Single Target Track, Ground Mapping, Ground Moving Target Indicator, etc. Submodes might be normal, one or two levels of doppler beam sharpening, track through notch, etc.
What the pilot sees on his HUD is dependent on which weapons he has selected. The FCS is not going to automatically switch from guns to missiles just because a target appears in the HUD.
The radar may switch modes automatically under certain scenarios, based on the range to the target. But it's sure as hell not going to be jumping around when the target is at a slant range of 1000'.
Under normal conditions, (modern) radar modes will be controlled by soft keys on the CRT. Automatic switching would be in cases where (for example) the target was within 12,000', the radar might switch from TWS to STT.

Okay right.
Anyway I enquired,apparently the "attack" mode(atk for short) is infact common to some Russian radars.It appears similar to the STT.But the radar will go into the Attack submode only if the missile parameters are met.And the submode is a common one ,meaning you can go to that submode from a number of other BVR and WVR modes.
Anyway in a close manouevring combat scenario there is a mode(I am talking about a particular radar) where you just need to place the opponent in your HUD and the radar will automatically lock on,and if the launching parameter of the missile you have selected are met it will go to the Attack submode with also an audible cue(beep) and then you can launch the missile.
I am not saying that the Hornet could have shot the Raptor in that scenorio.Just what could happen if you were using missile instead of the gun and not that it could switch from gun to missile.In anycase first the launch parameters of the missile have to be met.
