Laser beam-combined space debris removal system based on separated multiple-telescope form

Abstract

The invention discloses a laser beam-combined space debris removal system based on a separated multiple-telescope form, relates to the field of space technology and solves the problem that elements in optical paths are deformed due to heating in the process of space debris removal by the conventional ground high-energy laser emission system. According to the system, multiple beams of high-power lasers are emitted to space debris from the ground, and an ablation effect on the space debris is realized through the superposition of energy of the multiple laser beams. In order to improve the action effect of the laser beams on the space debris, the adaptive optical technology is adopted to correct optical element thermal deformation and disturbance caused by atmosphere in the system; meanwhile, the laser star guiding technology is used in the system, so that the action effect on faint space targets is improved. The space debris removal system is a manner for realizing the removal of space debris on the earth surface; the principle of energy superposition is used in the system, and multiple beams of lasers are used for emission, so that space debris at different orbit altitudes can be processed, the technology realization difficulty of each key unit is reduced, the maintenance is convenient and the cost is reduced correspondingly.

Description

technical field [0001] The invention relates to the field of space technology, in particular to the technology of removing space debris. Background technique [0002] Space debris refers to man-made objects orbiting around the center of the earth, which generally have no use value. It is the product of human space activities, including stopped spacecraft (such as satellites, space stations, space shuttles, etc.), rocket residues used to launch satellites, debris produced by the separation of multi-stage rockets, and collisions between space objects. fragments etc. With the progress of human space activities, the number of space debris presents a growing trend, and its potential collision risk seriously threatens the safe operation of spacecraft in orbit. [0003] Research on space debris focuses on monitoring and removal. To monitor space debris is to give its position and changes in the sky at every moment, and determine its orbit. Although for some regular space debris...
