摘要:

空间碎片对人类航天活动的危害很大,用高能激光减缓其危害性已受到广泛关注。针对地基激光清除椭圆轨道空间碎片问题,提出了单脉冲变轨和多脉冲变轨两种计算分析方法。仿真计算结果表明,碎片初始真近角在100°~150°附近降轨效果最佳;从激光器在地球表面可供布站的区域讲,在碎片真近角180°附近,布站区域最大;当推进激光总作用时间较短或作用距离较小时,单脉冲变轨计算模型和多脉冲变轨计算模型计算结果接近,因此可采用单脉冲变轨计算模型计算结果近似表示多脉冲作用效果。

Abstract:

Space debris poses great threat to human aviation activity. High power laser is considered a feasible method to clean it. Cleaning methods with single laser pulse and multi laser pulse orbitial variation are advanced in this paper based on an analysis of the removal of elliptical orbit space debris. The simulation results show that the initial true anomaly for effective de-orbiting effect is 100°-150° the widest range for ground-based laser distribution is at the vicinity of space debris true anomaly of 180° the two methods for de-orbiting space debris have very similar effects when the laser duration is extremely short or when the interaction distance is small, so that the single laser pulse orbitial variation method can be selected to represent approximately the multi-pluses method.

Key words: space debris, laser removal, single laser pulse, multi laser pulses, orbitial variation
