Abstract

The possibility of polarization selection implementation of the navigation objects located in the area of atmospheric formations by the ship single-position radiolocation station (radar) is considered. The polarization selection of the navigational objects located in the area of atmospheric formations is based on their different electro-physical parameters, which from them electromagnetic waves of different polarization. The process of the polarization selection is controlled by the appropriate choice of polarization, which irradiates the objects of the electromagnetic wave, given the actual Stokes parameters. The interference performance of the objects, observed by the ship’s radar, is represented by means of the Mueller matrices (i.e., dissociation), which have 16 coefficients. The determination of the matrix coefficients of the atmospheric formation dissociation is carried out by their differentiation or integration by the method of Pikar (i.e., the successive approximation). The coefficients of the atmospheric formation matrix are shown to be variable functions of time, endpoints for all values of the analyzed interval. The division of the time interval into segments, in which the coefficients of the matrix are considered constant, allows them to be calculated using Baker's formula. The practical implementation of the polarization selection of the navigation objects located in the zone of atmospheri formations, is based on the measurement of the coefficients of the dispersion matrix by the intermittent sampling of objects by non-polarized wave, double line wave, and circular polarization.
