Paper Abstract

The polarization structure research of millimeter waves is the urgent problem of plasma physics, radio communication, microwave geophysics, radioastronomy and it is a complicated problem in the radiophysics. The total polarization analysis of radio waves (as a rule stochastic and partially polarized) suggests a simultaneous or a quasisimultaneous measurement of four factors of coherency matrix or four Stokes parameters. In the millimeter waves region this type of analisys is performed extremely rarely and is characterized by low accuracy. A new differential method of a total polarization analysis presented by the author is mean of the space structure investigation of the arbitrary as well as slightly polarized waves. The method is based upon a quasisimultaneous wave decomposition in three orthogonal bases (two linear at 45° with respect to each other and one circular), switching of decomposition conditions, measurement of power difference of the orthogonally polarized components and on the construction of the Stokes parameters in the differential form [1]. The method suggested turned out especially effective in the millimeter wave region.
