摘要 |
A phase shift section phase-shifts the second band-restricted signal to a first phase-shifted signal and a second phase-shifted signal having a phase that is different from the phase of the first phase-shifted signal by 90 degrees. A first signal mixing section mixes the first band-restricted signal and the first phase-shifted signal. A second signal mixing section mixes the second band-restricted signal and the second phase-shifted signal. A phase difference calculation section calculates the phase difference value from the first mixed signal and the second mixed signal stripped of frequencies other than a desired baseband frequency. A polarization calculation section calculates reception polarization from the first reception field intensity value, second reception field intensity value and phase difference value. |
