radar altimeter[edit | edit source]
(Also called radio altimeter.) An onboard radar for determining the altitude of an aircraft above an underlying surface.
Pulse-radar techniques measure altitude in terms of the transit time of the radar pulse; continuous-wave radar measures altitude in terms of the phase difference between the transmitted and received signals.
