Abstract
Embodiments provide a landing and approach navigation system. The navigation system can use a radar system onboard an aircraft to transmit radio energy. A rotating reflector at a landing area can reflect the radio energy back to the radar system with an amplitude-modulation that is due to the rotation. With synchronized timing between the reflector and the radar system, and known rotation characteristics of the reflector, the radar system can use the reflected radio energy to calculate the bearing of the aircraft relative to the reflector and landing area.
