The optimal spacing of TR in AESA design is half wavelength which in turn results in a maximum 120 degree scanning FOV. The canting I believe allows some freedom of movement of the plate resulting in a higher FOV both in elevation and in azimuth. Canting is therefore a design choice to widen FOV without pointing the noseYes, but an AESA allows for canting of the nose-cone, which improves aerodynamics, doesn't it?
It was my understanding (correct me if I'm wrong) that because an AESA doesn't need to pivot mechanically, this allows for changes to the crossection to improve aerodynamics... I thought that was the reason why jets which are upgraded to an AESA usually also get a canted nose-cone...
p.s. as you pointed out this prototype doesnt even have a radar yet... so its possible when they install one it may come with a canted nose cone perhaps
In Western design, increasing situational awareness is via data linking rather than via individual platforms.
