Determining the polarization ellipse parameters of a multimode radiowave signal

A spectral-polarization method is proposed to determine the polarization-ellipse parameters of a radiowave signal in the wave front plane by analysis of three mutually orthogonal projections of the field vector. First, we calculate the complex Doppler spectra for the temporal variations of those projections. Then, these data are used to determine the polarization parameters of the electromagnetic wave for each spectral component. Formulas illustrating the proposed technique are presented, and the results of numerical simulation showing the possibility of practical implementation of the idea are given.
