Abstract (en)

[origin: EP4257475A1] The application relates to a life buoy, including a life buoy body, wherein a plurality of radar reflectors are arranged in the life buoy body; the plurality of radar reflectors are distributed in an annular array by using a center of the life buoy body as a center; each radar reflector includes a Luneburg lens and a reflecting piece; the Luneburg lens is made of a foamed dielectric material; a reflecting surface is formed on the reflecting piece; and the reflecting surface of the reflecting piece of each radar reflector is attached to a surface of the Luneburg lens. The application has the advantages of being simple in structure, scientific in design, convenient to use, and good in safety, and capable of displaying a large image on a radar screen, thereby avoiding search and rescue omission.
