Abstract
A radar altimeter having a tracking circuit which includes a controllable reference signal generator which is adapted to selectively control the tracking circuit so that there will be no indication of an altitude change in the event of a momentary loss of a received video signal due to the fading of the video signal or other condition requiring the locking of the tracking circuit because of a lack of reliability of the received video signal.
