62 and a corner reflector 63 that is built inside the ball and is expanded so that the adjacent surfaces of the plate members 64 become 90 ° when the folded state is released when the ball expands. 2, this apparatus is a cylinder 61 that automatically opens a valve when it is dropped into water and from which gas comes out, and a ball made of synthetic resin or vinyl that expands into a spherical shape by the gas in the cylinder. Patent Document 1 aims at a corner reflector device that is convenient for mounting on an aircraft or the like and that effectively functions as a search target even in the case of maritime distress. Such a corner reflector is already disclosed in Patent Document 1, for example. The corner reflector 51 is usually composed of two or three conductive plates 51a, which are combined so as to form 90 degrees with each other. 1, the “corner reflector” is a radio wave reflector that reflects radio waves in the incident direction regardless of the direction in which the radio waves 52 are incident. The present invention relates to an RF decoy, and more particularly to a folding corner reflector. COPYRIGHT: (C)2011,JPO&INPIT Description Translated from Japanese SOLUTION: The foldable corner reflector includes a hollow cylindrical main rod 12 having a concentric hollow hole at one end, a sub-rod 14 housed concentrically within the hollow hole and outward extendable along an axial line, four skeleton members 16 of which inner ends are attached to one end of the main rod and can swing from a folded position to an extended position, a radio reflection film 18 which is attached therebetween under a folded state and forms eight corner reflectors with a center at one end of the main rod under an extended position, and a circular extension device 20 which extends the sub-rod outward, swings the skeleton members from the folded position to the extended position, and extends an outer periphery of the radio reflection film 18 outward in the extended position. PROBLEM TO BE SOLVED: To provide a foldable corner reflector which can be ejected from an ejector to sky and three-dimensionally extended in air, is easily foldable and extendable, and has high radar reflection ability.
