Abstract: Disclosed is a helmet provided with a radar reflector. The helmet includes a helmet body formed in a shape corresponding to a shape of a user head, and the radar reflector mounted on an outer surface of the helmet body to reflect a radar signal transmitted from radar equipment. The radar reflector includes a plurality of reflection units each concaved in a trigonal pyramid shape having one opened surface, each of the plurality of reflection units reflecting the radar signal. Thus, by applying the radar reflector to the helmet of a user aboard an object to be detected by using a radar signal, the radar signal is effectively reflected in bad weather or at night, thereby improving the recognition rate of radar equipment.
