The paper investigates, with the help of the Stokes parameters, the polarization field structure of a retrodirective antenna array with the phase fluctuations in devices forming the orthogonal field components in the radiator aperture. Peculiarities of the Stokes parameters as applied in the statistical antenna theory are pointed out. Specificity of errors in the Van Atta arrays is noted, their influence on a degree of polarization and polarization pattern of a fully polarized component of the reradiated wave is studied.
