Abstract
A weather radar system improves electronics for receiving radar returns. The weather radar system determines an altitude above ground level using return data derived from the weather radar returns. The weather radar system can utilize movement data related to movement of the aircraft to calculate the altitude. In addition, the weather radar system can utilize previous calculations of the altitude to determine the current altitude underneath the aircraft. The weather radar system can reduce the need for a radio altimeter.
