APPARATUS FOR TRACKING POLARIZATION |
摘要 |
An apparatus for tracking polarized waves is provided to track the polarization of transmission signals to a satellite, thereby solving inconsistency of the polarization due to the change in the posture of a satellite or terrestrial terminal and the environment. A polarization tracking apparatus for reception comprises the followings: a feeder(303) which receives vertically and horizontally polarized waves to find out vertical and horizontal polarization factors; a polarization estimator(305) which estimates the deformation of polarization by using the vertical and horizontal polarization factors outputted from the feeder; a polarization controller(307) which controls the amplitude of vertically and horizontally polarized waves and phase information based on the estimated transformation information and signals; and a combiner(311) which combines the vertically and horizontally polarized waves controlled by the controller.
