Abstract
A system and methods for aligning an elliptical beam of an antenna to a line-of-sight from the antenna to a remote receiver are disclosed. The methods offset the antenna from an initial pointing direction in an antenna pointing coordinate system. Coordinates of the pointing offsets are determined in the E-plane and H-plane of an antenna beam coordinate system. The method then converts the coordinates of the pointing offsets from the antenna beam coordinate system into coordinates of offset points each located in the antenna pointing coordinate system according to the polarization angle of the E-plane and the H-plane, and performs a tracking algorithm using relative signal strength measurement data at the initial pointing directions and at the coordinates of the offset points. The true location of the center/peak of the elliptical beam is calculated in azimuth/elevation planes of the antenna pointing coordinate system.
