Patent ID: 7330151

Claim:
A method for aligning an elliptical beam of an antenna, having an antenna beam coordinate system, the method comprising: pointing the antenna to an initial pointing direction, wherein the initial pointing direction has coordinates in an antenna pointing coordinate system that includes an azimuth plane coordinate and an elevation plane coordinate; determining coordinates of E-plane pointing offsets relative to the initial pointing direction, wherein the coordinates of the E-plane pointing offsets are located in an E-plane of the antenna beam coordinate system; converting the coordinates of the E-plane pointing offsets from the antenna beam coordinate system into a first E-plane offset point and a second E-plane offset point, wherein each E-plane offset point is located in the antenna pointing coordinate system; determining coordinates of H-plane pointing offsets relative to the initial pointing direction, wherein the coordinates of the H-plane pointing offsets are located in an H-plane of the antenna beam coordinate system; converting the coordinates of the H-plane pointing offsets from the antenna beam coordinate system into a first H-plane offset point and a second H-plane offset point, wherein each H-plane offset point is located in the antenna pointing coordinate system; and calculating a true location of a peak of the elliptical beam in coordinates of the antenna pointing coordinate system.
