Embodiment 1
[0031] Such as figure 1 As shown, the corner reflector provided by the embodiment of the present invention includes: three square metal plates 101 , 102 , 103 and one baffle 104 . Wherein, the three square metal plates 101, 102, 103 are vertically connected in pairs, and there is a shared vertex in the three square metal plates 101, 102, 103 (such as figure 1 Vertex O) in and three shared connecting edges.
[0032] A baffle 104 is attached to each of the three square metal plates 101 , 102 , 103 . In specific implementation, the baffle may be a metal baffle.
[0033] In an optional embodiment, the baffle 104 may be a triangular baffle, and the three vertices of the triangular baffle (such as figure 1 The illustrated vertices e, f, g) each lie on the three common connecting edges.
[0034] Further, the triangular baffle may be an equilateral triangular baffle, and the distance b from the apex of the equilateral triangular baffle to the common vertex satisfies 0
Embodiment 2

Abstract
The invention discloses an RCS-controllable corner reflector and a design method, and relates to the technical field of radar. The corner reflector comprises three square metal plates and a baffle. The three square metal plates are perpendicularly connected in pairs, and the three square metal plates have a common vertex and three common connecting edges. The baffle is connected with each of the three square metal plates. According to the corner reflector, the baffle is additionally mounted on the basis of a square three-side corner reflector, so that compared with a traditional corner reflector of the same size, the RCS of the novel corner reflector is weakened, the order of the RCS can be reduced, and the need of generating low-order RCSs in practical engineering is met. By changing thesize of the baffle, the aim of being capable of controlling the RCS can be met, and therefore the need of generating different RCS order indexes in practical engineering can be met.
Description
technical field [0001] The invention relates to the technical field of radar, in particular to an RCS controllable corner reflector and a design method. Background technique [0002] The square trihedral reflector is a common analog unit in target design. Due to the stable structure of the square trihedral corner reflector, it can cause strong echo scattering in a wide range of angles, so it can be used as a radar echo enhancement device. [0003] In the process of realizing the present invention, the inventors of the present invention have found that: first, the RCS (radar cross-section) produced by the traditional square trihedral corner reflector is relatively large, which cannot meet the needs of generating lower-order RCS in actual engineering ; Second, the magnitude of RCS generated by the traditional square trihedral reflector is fixed, which cannot meet the needs of different RCS magnitude indicators in actual engineering. [0004] Therefore, to address the above d...
