ABSTRACT:
A dual-polarization receiver for receiving polarized wave signals whose directions are different from each other has receiving demodulation units of a working system and a backup system for one of the polarized wave signals, and receiving demodulation units of a working system and a backup system for the other of the polarized wave signals. RF local oscillation circuits of frequency converting circuits of the working system are connected with a common REF oscillation circuit and RF local oscillation circuits of frequency converting circuits of the backup system are connected with a common REF oscillation circuit.
