Your question doesn't make sense.. Both are pulse doppler radars.. The N011 has a slotted array antenna.

Slottet?
Doesn't the BARS array move sideways?

That kind of aperture is called the slotted array.

Slottet?Yes, the N011 is a slotted array radar.. the BARS is a PESA mounted on a gimbal/swahsplate in order to get wider FoV.

In dish antenna radar (like in F-4 etc. 60s/70s fighters), radar beam is focussed by reflecting it from dish shaped antenna.
In planar array (or slotted array), the antenna is flat, consisting of many small emitters, and radar beam is focussed by cleverly time shifting individual emitters. The antenna is then moved mechanically to steer the beam, just like in dish antenna radar.
In phased array, not only beam is focussed by phase shifting, it can be moved as well (see this wiki image), making mechanical steering unnecessary. Though some ESA radars still have mechanical steering as well.
