<p>[PROBLEMS] To provide a portable small-sized and lightweight radar wave reflection apparatus coming to a water surface to securely develop a function as a radar wave reflection apparatus when the apparatus is thrown or fallen into sea or water, having excellent radar wave reflection function as a radar wave reflection apparatus, and manufacturable at low cost. [MEANS FOR SOLVING PROBLEMS] This portable radar wave reflection apparatus comprises a high-pressure gas cylinder part, a gas release switch part for releasing high-pressure gas pressingly sealed in the high-pressure gas cylinder part, a column part expanded by the high-pressure gas released by the gas release switch part to form a hollow column, and a reflection part disposed at the tip of the column part, released by the release switch, and expanded by the gas led thereinto through the column part so that radar wave can be reflected thereon.</p> |
