radar altimeter

(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.
