FMCW Radio Altimeter

A radio altimeter is an electronic device that uses radar technology, i.e. electromagnetic waves in the high-frequency range to measure a distance. It is primarily used to determine height above ground and is therefore used to measure ground distance in avionics for flying objects. (more…)
