What is the difference between a radar altimeter and a barometric altimeter?

Radar altimeter gets altitude information by bouncing a radio wave off the surface of the Earth and determines the aircrafts altitude by measuring the length of time it takes for the signal to return. Barometric altimeters get altitude information by measuring the barometric air pressure outside the aircraft. Barometric pressure decreases as altitude increases. Radar altimeters will give altitude above ground level while barometric altimeters give altitude above sea level.
