"At close range or against targets using Jammers it is capable of narrowband interleaved search and track, which provides precise range and velocity that can then be used to shoot a missile without the need of the APG-81, allowing a 360 degree sphere of targeting other aircraft."
This is a little hard to parse. I still took that to mean that the system is operating in a passive mode and that if two conditions are met - very close range (and presumably quick bearing changes to average out ambiguities) or active jamming (presumably a more powerful signal? Or else potentially using a false target jamming mode against it self for localization? Hard to say). To me that still implies a passive track, although I still don't see how you could establish range without target speed. Maybe the speed can be extrapolated from doppler shift of the carrier wave plus bearing change? I'd hate to have to make THAT calculation by hand.
That said, that wouldn't exclude an active mode that created false targets (of F-35ish size) or other more specific push off/pull off deceptive modes, though in the case of the latter I'd expect the towed decoy to be the primary emitter as it implies a missile has a lock.
