Title:
【発明の名称】交さ偏波補償方式
Document Type and Number:
Japanese Patent JPS5953738
Kind Code:
B2
Abstract:
A cross polarization compensating system, in which two elliptically polarized waves of opposite polarities are applied to a cascade connection of two successively connected rotatable 90 DEG phase shifters and an Orthomode (Trademark) transducer. Two cross polarized wave components of the two elliptically polarized waves are detected from the two perpendicularly intersecting output terminals of the Orthomode (Trademark) transducer. Two in-phase components of the same phase as their co-polarized components of the two cross-polarized wave components and two orthogonal components each having a phase difference of 90 DEG from corresponding one of the co-polarized waves of the two cross-polarized wave components are detected from the two output terminals of the Orthomode (Trademark) transducer. One of the two phase shifters is controlled by an addition output of the two in-phase components while the other of the two phase shifters is controlled by a difference output between the two orthogonal components, so that two elliptically polarized waves at the output terminals of the Orthomode (Trademark) transducer are made equal in the cross polarization, and so that a phase difference between the co-polarized wave components and a phase difference between the cross-polarized wave components are made equal in magnitude and opposite in sign.
