Hm, on rather short notice I really don't find anything recent on a side-looking capability add to the APG-77. I've read something about passive side looking radar, whatever that means ...
The latest APG-77(V)1 has ground mapping SAR capability, here side looking arrays would come in handy, IMO, further increasing the Raptors ISR value.
I also wouldn't discount the Raptor's tactical mini AWACS role that fast. It's stealth allows it to penetrate hostile lines and then optain some usefull information of airops. It can perhaps also direct other groups or guide handed off missiles. It could also, after having a quick look, switch off again and run. When it's not emmiting anymore, it's rather difficult to pinpoint a VLO object travelling at M1.5 at 60.000ft without two glowing candles at it's back.
