NAVIGATION RADIO-OPTICAL POLARIZATION-ANISOTROPIC CORNER REFLECTOR OF DIRECTIONAL ACTION WITH LIGHT-REFLECTING FACES Russian patent published in 2022 - IPC H01Q15/18 

FIELD: optics; radio engineering.

SUBSTANCE: navigation radio-optical polarization-anisotropic corner reflector of directional action with light-reflecting faces is a triangular corner reflector with triangular faces of the same dimensions, coated on their inner side with a radiotransparent light-reflecting coating with white, red, green or yellow glow colors, two lateral triangular faces of which are made in the form of a metal or metallized reflecting surface, and the third lower triangular face, in order to impart polarization-anisotropic properties to the corner reflector, is made in the form of a horizontally located polarization array consisting of parallel round metal conductors. At the top of the corner reflector there is a light source in the form of a light-emitting semiconductor diode, the emission color of which corresponds to the color of the light-reflecting coating of the faces.

EFFECT: simultaneous operation is achieved not only on waves with linear polarization, but also on waves having circular polarization of left or right direction of rotation, on which radars operate with parallel reception.
