NAVIGATIONAL RADIO-OPTICAL POLARIZATION ANISOTROPIC DIRECTIONAL REFLECTOR WITH REFLECTIVE TRIANGULAR FACES Russian patent published in 2023 - IPC H01Q15/18 

FIELD: radio engineering.

SUBSTANCE: invention is related specifically to radio navigation, namely to navigational radio-optical corner reflectors. The result is achieved due to the fact that the directional reflector is a trihedral corner reflector with triangular faces of the same size, covered on their inner side with a radio-transparent reflective coating with white, red, green or yellow glow colours, two side triangular faces which are metal or metallized reflecting surfaces, and the third lower triangular face, in order to ensure polarization-anisotropic properties of the corner reflector, is made in the form of a polarization grating consisting of parallel round metal conductors oriented at an angle of 45° to the edge of the lower face of the corner reflector coinciding with the horizontal plane.

EFFECT: simultaneous operation of a radio-optical polarization-anisotropic reflector in the radar wave range: on waves with horizontal linear polarization, on waves with circular polarizations of the left or right direction of rotation, and on waves with vertical polarization.
