ある。2. Description of the Related Art A radar reflector used for a homing performance test target of a radar homing vehicle or a rescue buoy searched by a radar has a hollow triangular pyramid shape having an open bottom surface and has three slopes formed on each other. There is a type in which a number of reflector elements each having an opposing surface as a radio wave reflecting surface are arranged in a polyhedral shape with their open surfaces facing outward.

の入射方向と平行な方向に出射して行く。This radar reflector reflects a radio wave emitted from a radio wave emitting source such as a radar homing flying body toward the above-mentioned radio wave emitting source, and a radio wave incident on a reflector element having a hollow triangular pyramid shape is The light is sequentially reflected by the three reflecting surfaces of the reflector element and is emitted in a direction parallel to the direction of incidence on the reflector element.

という問題をもっている。[0004] There are two types of radar reflectors, one having a rigid structure and the other having a stretchable type. A rigid-structure reflector has a structure in which each reflector element includes a metal plate such as an aluminum plate.
Alternatively, it is formed of a hard reflecting plate made of a hard resin plate or the like having a radio wave reflecting coating on its surface, and each reflector element is arranged in a polyhedral shape and rigidly joined.
However, since the reflector having the rigid structure has the reflector elements rigidly connected to each other, there is a problem that transportation is troublesome.

(多面球の各頂部)を結合した構造となっている。On the other hand, in the case of a stretchable reflector, each reflector element is formed of a flexible reflective film, and each reflector element is arranged in a polyhedral form. Each reflector (the top of the polyhedron) is connected to each top balloon of the reflector main body.

ができる。This expandable reflector is used by inflating the balloon by injecting air into the balloon to expand the reflector body in a polyhedral shape. This reflector removes air from the balloon. Accordingly, the reflector main body can be folded together with the balloon, so that the entire reflector can be reduced in size to be easily transported.

特性が得にくくなるという問題をもっている。However, since the above-mentioned conventional expandable reflector expands the reflector main body by inflating the balloon, each reflector element is balanced with an equal expansion tension when the reflector main body is expanded. There is a problem that it is difficult to expand well, so that each reflector element expands in a distorted state, and it is difficult to obtain good radio wave reflection characteristics.

A triangular area having the tops of the two upper aggregates and one lower aggregate as vertices And the reflector elements arranged in the two lower aggregates and in the triangular region having the top of one upper aggregate as the apex, the three apexes of the open edges of the reflector elements are provided at the tips of the respective aggregates. Each of the reflectors is fixed and supported by these aggregates, and the apex of each of these reflector elements is supported by a support of the bone structure. Other reflector radar, characterized in that coupled to the slide member.
