1. A method of adjusting a position of an antenna to reduce a position error, the method comprising:
- receiving first data associated with first returns associated with a first portion of an antenna;
receiving second data associated with second returns associated with a second portion of the antenna, wherein the first portion is entirely different than, intersects with or includes the second portion, the first portion and the second portion not being the same, wherein the first portion includes all of the antenna or a portion of the antenna; and
determining an angle to terrain using the first and second data, whereby the angle is used to compensate or adjust the position of the antenna to reduce the position error.

Abstract
A method of adjusting a position of an antenna to reduce a position error comprises receiving first data associated with first returns associated with a first portion of an antenna. The method further comprises receiving second data associated with second returns associated with a second portion of the antenna, wherein the first portion is different than, intersects with, or includes the second portion. The method further comprises determining the angle to the terrain using the first and second data, whereby the angle is used to adjust or compensate for the position error of the antenna.

12. An apparatus, comprising:
-
a radar antenna for receiving radar returns from a target; means for receiving first data associated with first returns associated with a first portion of an antenna; means for receiving second data associated with second returns associated with a second portion of an antenna, wherein the first portion includes the second portion, intersects the second portion, or is exclusive of the second portion; and means for determining an angle within a beam to the terrain using the first and second data and using the angle to adjust or compensate antenna position to reduce radar antenna position errors.
