Abstract
Systems and methods are provided for determining a polarization state of an input RF signal. Two distinct RF antennas receive the input RF signal and output a first antenna signal and a second antenna signal. Polarizsations of the first and second antenna signals are orthogonal to one another. The first antenna signal is converted to a first optical signal, and the first optical signal is passed through a first optical signal to introduce a first delay. The delayed first optical signal is converted to a first RF signal. An amplitude ratio and a phase difference are determined between the first RF signal and a second RF signal that is associated with the second antenna and optionally includes a second delay. A polarization angle or polarization type of the input RF signal is determined based on the amplitude ratio and phase difference of the first and second RF signals.
