Both Polarization Transmission System, Both Polarization Receiving Apparatus, Both Polarization Transmitting Apparatus, Polarization Wavefront Controlling Method, and Polarization Wavefront Control Program

摘要

To provide a dual polarization transmission system and the like which prevents deterioration of extreme transmission characteristics in one of V polarization and H polarization without involving physical rotation of an antenna.SOLUTION: In both polarization transmission systems, the receiver 3 determines whether there is a difference equal to or larger than a threshold value previously given to the electric field intensities of the signals on the V polarization side and the H polarization side received by the antenna 3a An electric field difference detector 4 for detecting whether or not the electric field intensities of the signals on the V polarized wave side and the H polarized wave side are equal to or larger than a threshold value, And a receiver, a calculation corresponding to rotation of the antenna by the rotation angle is performed on each of the signals on the V polarization side and the H polarization side according to the instruction An angle inverse operation section 6, and a demodulator 7 for demodulating and outputting each signal outputted from the angle inverse operation section.(FIG.
