How the E-3 AWACS Sees Every Plane Within 400 km (3D)

How does the E-3 AWACS see every plane within 400 km? A 3D x-ray look inside the Boeing E-3 Sentry: the rotating radar dome, the antenna hidden inside it, the pulse-Doppler radar that finds low-flying jets against the ground, the IFF friend-or-foe system, the crew consoles and how one aircraft watches an entire sky. Airborne early warning and radar engineering explained in 3D animation.
