Embodiment Construction

[0039] The specific embodiment of the present invention is as figure 1 shown.

[0040] The self-adaptive laser derotation system proposed by the present invention is composed of an electric turntable 36 and a fuselage main body 37. The fuselage main body 37 contains an image tracking subsystem 5, a tracking analysis subsystem 6, a distance measuring and speed measuring laser emitting subsystem 21, an echo Receiving subsystem 7, LID subsystem 12, LID effect monitoring and analysis subsystem 10, adaptive focusing subsystem 29 and main control analyzer 11;

[0041] Among them, the electric turntable 36 can accept the instruction of the main control analyzer 11 to drive the main body 37 of the fuselage to rotate at any angle in three dimensions;

[0042] The image tracking subsystem 5 is made up of a wide-angle lens 31 and an imaging detector 32; the tracking analysis subsystem 6 is made up of an imaging controller 34 and an imaging analyzer 35; the imaging controller 34 communic...

Abstract

The invention discloses a self-adaptive laser despinning system for space debris. The system is composed of an electric rotary table and a machine body. The machine body is internally provided with an image tracking sub-system, a tracking analysis sub-system, a distance and speed measuring laser emission sub-system, an echo receiving sub-system, an LID sub-system, an LID effect monitoring and analyzing sub-system, a self-adaptive focusing sub-system and a main control analyzer. The self-adaptive laser despinning system for space debris has the beneficial effects that the image tracking sub-system is used for real-time analysis of distribution of space debris and selection of debris target of interest. A variable-power multi-pulse LID laser, the distance and speed measuring laser emission sub-system and the LID effect monitoring and analyzing sub-system are adopted, so that self-adaptive debris speed reduction and despinning are achieved, rapid debris despinning is achieved, and the debris capturing capacity is improved.

Description

technical field [0001] The invention relates to a laser derotation system and method, in particular to a target derotation system and method using composite laser and imaging means, which is suitable for derotation of low earth orbit debris and belongs to the field of optoelectronic technology. Background technique [0002] The collection of invalid objects in Earth orbit is called space debris (Space debris), also known as orbital debris, space junk or space waste. There are 1,500 large fragments (each with a mass greater than 100 kilograms) in the Low Earth orbit (LEO for short), whose total mass accounts for 98% of the total mass of the entire low-orbit fragments (1,900 kg). [0003] Every satellite launch, space exploration and manned spaceflight may produce residual space debris. Any collision between two space objects of a certain size will produce new debris. Especially when a large collision (such as a space station and a failed satellite) occurs, the large amount ...
