No, it really shouldn't. The radar beam, especially at long ranges, is pretty big. Assuming similar performance to the APG-63 (gimbal-speed wise) there might be a maximum of four seconds between dwells.
A fighter won't maneuver out of the radar coverage in four seconds, and even if he would, the radar would go into memory mode and start a grid-search in the vicinity of the last known vector.
At really close range you might experience a dropped track, but at that point you would've switched to STT already anyways.
