Abstract: A polarimeter includes a receiver that is configured to receive a first polarization (P1) of the signal and to split the first polarization of the signal into the in-phase (IP1) and quadrature (QP1) components and to receive a second polarization (P2) of the signal and to split the second polarization of the signal into the in-phase (IP2) and quadrature (QP2) components. The polarimeter may also include a processor that is configured to receive each of the in-phase and quadrature components ((IP1), (QP1), (IP2), and (QP2)) of the first and second polarizations and to determine the Stokes polarization vector components (s0, s1, s2, and s3) of the signal.

Abstract: A correlating polarimeter is provided for correlating a received waveform of a wideband electromagnetic signal with a predetermined waveform. The correlating polarimeter may include a first antenna for receiving an electromagnetic signal and a modulator interconnected with the first antenna for modulating the electromagnetic signal whereby a modulated electromagnetic signal results which contains a different polarization state for each frequency of the electromagnetic signal with the amplitude of each frequency component of the modulated electromagnetic signal being a function of the particular polarization state of each frequency component of the electromagnetic signal.
