Does not matter what you mean by the "most advanced mechanical radar". Its still a mechanical radar, and the array does not multitask its scanning like phase array and AESA does. Go ahead and explain to me how a slotted array can split its beams and head them to different directions when its the mechanical arm behind the array that points the array and turns it around.
I simple repeated what the magazine said, the author do not porvide technical explanation how the slotted array radar able to performed this feat.
rather all there information come from both manufacturer and the pilot.
