AI Technical Summary

Technical Problem

Existing radar reflectors on small fishing boats are ineffective at reflecting radar waves, leading to frequent collisions and detection failures, and existing inflatable reflectors face limitations in size and connectivity of internal reflectors, with fixed installation positions hindering their use in emergency situations.

Method used

An inflatable radar reflector with an expandable main body facilitated by fluid injection, using elastic connecting members to maintain a predetermined shape and arrange multiple reflectors, and incorporating a light-emitting element powered by a seawater battery for increased visibility and rescue efficiency.

Benefits of technology

Enhances radar wave reflection efficiency, improves rescue probability by increasing radar wave incidence, and ensures visibility at night, with the light-emitting feature aiding rapid rescue efforts even during prolonged operations.

Abstract

To provide an inflatable radar reflector that facilitates the expansion of the main body and facilitates the reflection of radar waves. [Solution] The present invention includes a body formed to expand internally via fluid injection; a reflector provided inside the body, formed such that its upper and lower parts are symmetrically shaped like a "+" sign, for reflecting radar waves upon incidence; a plurality of elastic connecting members for connecting each corner portion of the "+" shape of the reflector to the inside of the body; and a case in which the body is stored in a folded or rolled state, wherein when fluid is injected into the body pulled out of the case, each corner portion of the reflector is pulled by the elasticity of the connecting members, and the reflector is maintained in a predetermined shape when the expansion of the body is complete.
