Statistical Properties of Polarization Parameters of Radio Signals and Noise

To estimate the noise stability of communication systems in which polarized manipulation of signals is used, it is necessary to know the statistical structure of partially polarized waves. Probability density distributions are obtained for the geometric parameters of the polarization ellipse of a quasimonochromatic partially polarized wave for a circular and linear basis of representation of this wave. It is shown that for practical applications the more convenient one to use is the density distribution obtained from the circular basis of representation.
