ANALYSIS OF THE EFFECT OF SIGNAL POLARIZATION CHARACTERISTICS ON THE NOISE REDUCTION COEFFICIENT

The paper considers the possibility of using polarization characteristics to perform interference suppression tasks. The polarization characteristics and their effect on the signal-to-noise ratio are analyzed. The mutual influence of the coefficients of ellipticity of the signal and interference, the angle of spatial orientation of the axes of the ellipses of the signal and interference, and the direction of rotation of the electric field strength vector when performing tasks of polarization selection are considered. Graphs of the signal-to-noise ratio dependences on the polarization characteristics are constructed. The possibility of using the polarization characteristics of the received signals for selection when performing interference suppression tasks is shown. The range of changes in the values of the polarization characteristics is determined for the most effective selection, as well as having the least effect on the signal-to-noise ratio. Keywords: polarization selection, polarization characteristics, ellipticity coefficient, polarization coefficient, signal-to-noise ratio, angle of spatial orientation of the polarization ellipse.
