Abstract: A radar reflector for buoys and other floating objects comprising six identical corner reflectors circumferentially evenly spaced about the main reflector axis. The axes of symmetry of said six corner reflectors define angles of about 90.degree. with said main reflector axis and the apertures of said corner reflectors are outwardly directed and alternatingly disposed in inverted relation with respect to one another. The three plates of each corner reflector are enlarged up to the intersection lines with the plates of adjacent corner reflectors and to the intersection line, respectively, with an assumed cylinder surface circumscribing the total reflector assembly.
