ABSTRACT:
A system and method for sensing elevation terrain using an airborne weather radar. Method techniques include sampling first and second radar returns from a weather radar at two portions of an antenna. First radar returns are removed from second radar returns to generate third radar returns for a third portion of the antenna. The third portion of the antenna is included in the second portion but not the first portion. Changes in the third radar return are analyzed to sense elevation of the terrain.
