Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of space non-cooperative target tracking and sighting integration, and particularly relates to a space debris detection, tracking and sighting and laser emission common-caliber optical system. BACKGROUND

[0002] Space debris is "space garbage" caused by collisions, actions, damages between space flight devices or space human activities, and is a typical space non-cooperative target. Because the space debris is numerous in space, covers a large size range and is difficult to realize full traversal and cataloging, the space debris causes an increase in space random events and poses a great threat to space safety. Compared with continuous monitoring to realize collision avoidance, the removal of space debris is an effective and one-time solution to the problem.

[0003] In recent years, with the continuous progress of human space technology and the continuous acceleration of space activities, more and more spacecrafts are sent into space. At present, the number of cataloged debris in space has reached tens of thousands, and the number is still accelerating. According to foreign prediction results and Kessler effect estimation, the number of space debris will continue to accelerate in the next few hundred years. If not controlled, the Earth's orbit will eventually become unusable due to the cascade reaction caused by the concentration of debris, resulting in irreversible consequences. Therefore, it is urgent to study the space debris removal technology. Space powers or organizations such as the European Union, the United States, Japan and Russia have proposed space debris active removal plans. The European Space Agency will launch the world's first space debris orbit removal mission in 2025. China has also been very concerned about space debris removal and space environment management, and has established relevant organizations to gather national forces to conduct research from target observation, space-ground cooperation, active removal and other aspects.

[0004] The laser active removal of space debris technology is one of the many space debris active removal schemes. In the laser active removal of debris means, the key is the detection, accurate tracking and long-distance action of small non-cooperative targets in space. The debris has complex sources, different sizes, various shapes and complex target characteristics, and the detection, identification and aiming of centimeter-level small debris are more difficult. For debris search and monitoring, high-resolution passive optical imaging technology is needed. For accurate aiming of the debris target, active optical assistance is needed for optical positioning. In order to ensure the removal effect, the target position needs to be very accurate, and the transmission and reception coaxial system can effectively improve the system action accuracy. In view of the above needs, a high-integrated active and passive tracking and sighting system is needed to realize the laser active removal of space debris. SUMMARY

BRIEF DESCRIPTION OF DRAWINGS

[0018] Various other advantages and benefits will become apparent to those of ordinary skill in the art upon reading the following detailed description of the preferred embodiments. The detailed description is made with reference to the accompanying drawings.

[0019] Figure 1 FIG. 1 is a structural schematic diagram of a space debris detection and tracking and laser emission common aperture optical system provided by an embodiment of the application. DETAILED DESCRIPTION

[0020] Exemplary embodiments of the present disclosure will be described in detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] From the current technical status, in the whole space debris laser active removal process, the task flow needs to be considered comprehensively. On the one hand, the large field of view angle is needed for the search process of a large sky area, and the larger the aperture of the passive receiving system is, the larger the image size is. After the search is completed, the high-resolution imaging of the micro debris target also puts forward higher requirements for the receiving pixels. On the other hand, in order to realize the effect of the debris at a long distance, the energy concentration degree of the laser far field spot at the action point should be ensured, which puts forward new requirements for the whole laser transmitting system, and the coupling difficulty of the optical system increases. For the application scene, the target to be measured needs to be determined under the premise of providing a certain prior pointing range. Based on the difficulty of capturing and tracking the micro centimeter debris, in the space observation range of ten kilometers to one hundred kilometers, according to the analysis needs, the pixel angular resolution and tracking accuracy of the order of μrad should be met. On this basis, because the coarse and fine tracking resolutions are different, the system should meet the field of view angle of the order of mrad required by the fine tracking in the progressive observation process. At the same time, because the size of the centimeter target is very small, the target prior information (shape, attitude, etc.) is insufficient, the coupling laser ranging unit should realize the collimating emission of the same aperture to meet the high tracking accuracy multiplexing, and the coupling laser transmitting unit should meet the energy concentration degree and radiation energy required by the debris removal. In the system, the size of the far field laser converging spot at the transmitting distance is required to be coupled with the target size optimally (1-10 cm), and the transmitting end energy parameter should also consider the laser setting parameter.
