一种高效利用天基激光能量清除空间碎片的方法

针对日益增长的空间碎片污染太空环境问题，建立了天基激光能量清除空间碎片的降轨模型。重点讨论了速度增量与空间碎片速度的夹角对近地点高度降低的影响，并考虑到天基平台与空间碎片作用距离的影响，从能量利用率的角度出发，提出了能量分配系数（CEA）的概念。基于CEA，设计出关于脉冲激光能量分配的策略，并与脉冲激光能量平均方式清除空间碎片的方式进行对比分析，说明了脉冲激光能量分配策略的有效性，提高了天基激光能量利用能力，达到了高效清除空间碎片的目的。

A method of efficiently using space-based laser energy to remove space debris

In view of the growing space debris pollution of space environment, the deorbit model of space-based laser removal of space debris is established. In this model, the effect of the angle between the speed increment and the space debris velocity on the height reduction of perigee is emphatically analyzed, and taking into account the influence of the distance between them, the concept of coefficient of energy assignment (CEA) is proposed from the perspective of energy utilization. According to the CEA, a pulsed laser energy assignment strategy is designed, and it can improve the energy utilization ability to remove space debris more efficiently compared with the way of average energy laser pulse cleaning space debris, illustrating the effectiveness of our removal strategy.
