NAVIGATION RADIO-OPTICAL ANGLE REFLECTOR OF DIRECTED ACTION WITH TRIANGULAR FACES COATED WITH ALUMINIUM FOIL Russian patent published in 2019 - IPC H01Q15/18 

FIELD: physics.

SUBSTANCE: invention relates to radio navigation and can be used on inland waterways as a part of linear cross-sections to indicate navigation stroke simultaneously in radar and optical ranges of waves. Navigation radio-optical angle reflector of directed action represents a trihedral angular reflector with triangular faces coated with aluminium foil. At the corner of the angle reflector there is a light source in the form of a light-emitting semiconductor diode, the radiation colour of which corresponds to the white, red, green or yellow colours of the signal light and is determined by the prevailing navigation environment. Light source is powered by a DC power supply and is controlled by the signal fire control photocell.

EFFECT: technical result is expansion of functional capabilities of the radio-optical angle reflector in the optical wave range, caused by supply of light-signal lights with white, red, green or yellow glow colours when using the same reflecting inner surfaces of triangular faces coated with aluminium foil, wherein the colour of the signal light is set only by the type of the light-emitting diode and is determined by the existing navigation environment on the waterways; wherein the aluminium foil is used simultaneously both in the radar range of waves as the reflective coating of the navigation mark, and in the optical wave band as a reflective light-reflecting coating.
