The purpose of this research is to develop and analyze certain technical solutions on the composition of elements and devices of the ship radar polarization complex (SRPC), increasing its functional capabilities in complex conditions of the atmospheric environment. This paper substantiates the methodology of SRPC construction, which includes a six-channel waveguide polarization splitter. The methodology of this research is aimed at solving the issues relating to the development of the main high-frequency nodes of the considered splitter and the mathematical description of the relations between the field components in the splitter. The structure of the SRPC construction defines the nature of connections and relations between the elements of the functional scheme as a whole, and the rearrangement of the structure includes methods that characterize the change in the composition and functional interaction of its parts depending on the performance of the task of polarization selection of echo-signals of the navigation object located in complex atmospheric conditions on the ship’s route. Elements included in the SRPC and devices of the all-polarized antenna allow for radiating electromagnetic waves of linear and circular polarizations, as well as unpolarized waves, to analyze polarization parameters of echo signals of complex objects to solve problems of polarization selection of navigation objects located in the zone of dangerous atmospheric formations. A six-channel polarization splitter in the waveguide channel of the SRPC antenna splits the polarized components of the analyzed partially polarized wave arriving at the input of the all-polarized antenna into six channels to ensure the symmetry of its two orthogonally polarized components. The two-channel linear receiver amplifies and transforms orthogonal components of the electromagnetic wave echo signal for each polarization of the radiated wave and forms energetic actual Stokes parameters that allow for solving problems of polarization selection of navigation objects located in complex atmospheric conditions along the ship’s trajectory. Polarization selection provides the formation and consistent radiation of constant power electromagnetic waves of four polarizations (three linear and one circular), as well as an unpolarized wave. As a result of the research performed on the development of a six-channel waveguide polarization splitter, the problem of increasing the efficiency of ship radar stations functioning with the use of methods of polarization selection of navigation objects and improvement of radar equipment is solved.
