A method for main beam alignment verification includes providing data pertaining to one or more patterns associated with an antenna, measuring power levels of a signal acquired by the antenna, and comparing the measured power levels with the data to determine whether a direction of the signal is incident upon a main beam of the antenna.

Main beam alignment verification for tracking antennas

A method includes determining if a dynamics requirement for an antenna positioner is exceeded, and employing a combination of mechanical and electronic beam steering techniques to steer a single antenna beam if the dynamics requirement is exceeded.

System and method for antenna tracking

Methods and systems for tracking signals with diverse polarization properties address both sensitivity and antenna tracking performance issues. In one embodiment, complex weightings for matching a polarization of an incident signal on a data channel are determined, and the complex weightings are applied to a tracking channel such that an antenna system polarization is matched to the polarization of the incident signal. In another embodiment, orthogonally polarized tracking channel components of an incident signal are processed to make a determination as to which of the orthogonally polarized tracking channel components is stronger, and this determination is used to select a polarization of a data channel to reduce a polarization mismatch loss.

Antenna beam steering and tracking techniques

A method for antenna tracking includes providing a central feed element in an antenna focal region with additional feed elements in an azimuth coordinate to provide a multitude of feed elements that each have a static beam position, and varying ratios of amplitudes of adjacent feed elements of the multitude of feed elements to electronically steer a beam between the static beam positions.

A method of tracking a signal from a moving signal source including commanding angular offsets to control an antenna to track a signal from a moving signal source taking into consideration directional changes of the signal and comparisons between actual and estimated trajectories of the moving signal source.
