Title: Cross-polarization compensation
Inventor: MARUMOTO TSUNEHISA
IPC: H01Q15/24
Filed: 1994-10-31
Abstract: In an earth station terminal, a cascaded arrangement of downlink half- and quarter-wave polarizers receives a downlink communication signal and a mono-polarized beacon signal from a communications satellite and separates the communication signal into respective polarization components. A receiver is connected to the cascaded polarizers for detecting the in-phase and orthogonal-phase components of a cross-polarization of the beacon signal with respect to the phase of its copolarization. For cross polarization compensation, first and second polarization offset values of the beacon signal are derived from the angular positions of the polarizers, and subtracted from the beacon's in-phase and orthogonal-phase components, respectively, to produce target values. By controlling the polarizers until their angular positions are respectively equal to the target values, the polarization components of the downlink communication signal assume zero vectors.
