Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as figure 2 As shown, the present invention is suitable for a cooperative target device for rendezvous and docking optical imaging sensors and laser radars, comprising: a central corner cube 1, N edge corner cubes 2, a ring filter 4, and a cooperative target housing 4 , N edge corner cubes 2 are symmetrically distributed around the central corner cube 1, the refracting surfaces of N edge corner cubes 2 are coplanarly arranged, and the effective diameters of N edge corner cubes 2 are the same, and N can be 6 or 12. The field angle range of any corner cube in the N edge corner cubes 2 is not less than -16 degrees to 16 degrees.

[0025] The ring filter 3 completely covers the refractive surfaces of the N edge corner cubes, the hollow part is used to avoid blocking the refractive surface of the central corner cube 1, and the cooperati...

Abstract

The invention relates to a cooperative target device applicable to a rendezvous and docking optical imaging sensor and laser radar. The cooperative target device comprises a single central cube-corner prism, N edge cube-corner prisms, an annular light filter and a cooperative target casing. When laser radar is used for measurement, only the central cube-corner prism returns light, and the field angle ranges from -20 degrees to 20 degrees; when the rendezvous and docking optical imaging sensor is used for measurement, the central cube-corner prism and the edge cube-corner prism array return light simultaneously, and the field angle ranges from -16 degrees to 16 degrees; a measurement basis is designed on the cooperative target casing and used for representing measurement coordinate systems of the rendezvous and docking optical imaging sensor and the laser radar. The cooperative target device can be used for the rendezvous and docking optical imaging sensor and the laser radar simultaneously, can reduce the layout difficulty of rendezvous and docking aircrafts, the smallest work distance between the two sensors can reach 0.5 m for docking, and the reliability of a rendezvous and docking mode is improved.

Description

technical field [0001] The invention relates to a cooperative target device suitable for rendezvous and docking of relative navigation sensors, in particular to a cooperative target device for rendezvous and docking of optical imaging sensors and laser radars. Background technique [0002] Space rendezvous and docking missions generally use lidar and rendezvous and docking optical imaging sensors as rendezvous measurement sensors in the short-to-medium range to the completion of docking. Lidar can provide relative motion parameters between two aircraft within a relative distance of 20km to 0.5m; rendezvous and docking optical imaging sensors can provide high-precision six-degree-of-freedom relative pose navigation information between two aircraft within a range of 150m to 0.5m . In the past, the laser radar and the rendezvous and docking optical imaging sensor used the cooperative target design to measure their respective cooperative targets. The shortest working distance ...
