Problems solved by technology
However, due to the inherent influence of the launch system, the projectiles will produce a large dispersion area. No matter how the corner reflectors are discharged, there is no guarantee that each projectile will face the corner reflectors and land in front of the corner reflectors.

Embodiment Construction
[0026] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0027] The purpose of the present invention is to propose the design of the test target of the missile-borne seeker---the corner reflector, so that the pattern bandwidth between two adjacent corner reflectors can be continuous, thereby forming a continuous spherical corner reflector . It is used to solve the problem that when the missile-borne seeker is flying in the air, the missile-borne radar seeker can detect and capture the target when the projectile flies in different directions and different angles of incidence.
[0028] In order to achieve the above objectives, the present invention adopts a structural form in which a plurality of identical corner reflectors have a spatial positional relationship. The spatial position is divided into three layers. The bottom corner reflectors have 12 identical triangular corner reflectors installed on a circular bottom p...

The invention relates to a multi-layer spherical corner reflector device. A spherical corner reflector is divided into three layers. The central pointing angle of the bottom angle reflector unit is 15 degrees and is smaller than that of the middle angle reflection unit by 30 degrees; the central pointing angle of the middle corner reflector is smaller than that of the top angle reflector by 30 degrees; and reflector bodies in each layer are distributed uniformly at an equal 30-degree angle along the peripheral direction. Because the spherical corner reflector serves as a ground test target during flight of a seeker, a problem that the width of the directional diagram of the single-quadrant corner reflector is not continuous can be solved effectively. Therefore, when a missile-borne seeker flies from different directions of the spherical corner reflector, the seeker can search a target; and on the basis of the design of the spherical corner reflector device, a testing demand of a seeker is satisfied and the number of times of non-effective flight of the seeker can be reduced.
Description
technical field [0001] The invention belongs to the technical field of mechanoelectronics, specifically, when designing a corner reflector, the test target of a seeker, a plurality of corner reflector units are uniformly arranged at equal angles in space to form a spherical corner reflector. Background technique [0002] The radar corner reflector is usually a rigid structure composed of three mutually perpendicular metal surfaces. Due to its special geometric structure, the incident electromagnetic wave can generate multiple internal reflections inside it, and finally the radar beam is reflected back along the incident direction (see figure 1 ). The geometric structure of the trihedral corner reflector itself is stable, and the plates are orthogonal to each other, which can produce strong echo scattering in a wide range of angles, that is, it has a large RCS, so the practical application of the trihedral corner reflector is the most extensive. [0003] There are three comm...
