NAVIGATION RADIO-OPTICAL GROUP REFLECTOR OF CIRCULAR ACTION IN HORIZONTAL PLANE WITH FACES COVERED WITH ALUMINUM FOIL Russian patent published in 2021 - IPC H01Q15/18 

FIELD: navigation.

SUBSTANCE: invention relates to navigation. A navigation radio-optical group reflector of circular action in the horizontal plane with faces covered with aluminum foil is a group radar reflector having eight triangular corner reflectors with equal triangular faces six of which are located around the vertical axis passing through their coinciding vertices perpendicular to the horizontal plane and form the backscatter diagram in the radar wavelength range. The backscatter diagram is circular in the horizontal plane. In this case, the reflective triangular faces of all six triangular corner reflectors from their inner side are covered with a reflective coating made in the form of aluminum foil. For the formation in the optical wavelength range of the circular backscatter diagram in the horizontal plane in the center of fit of the vertices of six triangular corner reflectors, which is their common focus in the optical wavelength range and the phase center of scattering in the radar wavelength range, a light source is installed made in the form of a light-emitting semiconductor diode with white, red, green or yellow colors of the signal light glow with directional characteristics of radiation in the vertical plane and omnidirectional radiation angle in the horizontal plane. The light source is powered by a DC power supply and is controlled by photo-automatic control of a signal light. To supply light signal lights omnidirectional in the horizontal plane at night, only one light source with omnidirectional radiation characteristics in this plane is used. The light source is installed at the fit point of the vertices of the triangular corner reflectors included in the group.

EFFECT: design simplification.
