"Debate rages between rival radar houses about the pros and cons of repositioning AESA arrays, but Hilditch said, “We’ve done a lot of work on the e-scan proposal.”

Interesting. By definition, if it moves mechanically, it is not a true AESA radar.

I would hazard a guess that they reposition it to avoid beam broadening and loss of ERP at extreme scan angles.

“I would hazard a guess that they reposition it to avoid beam broadening and loss of ERP at extreme scan angles.”

Just think about a formation of 4 aircraft with each aircraft’s radar mechanically looking in a different direction. Even with same radar output power the detection range is increased against a fixed AESA with equivalent power.
