摘要
不考虑空间目标共轨道面或近似共面的情况下,两个空间目标轨道面都存在交线,且两个空间目标可能交会的地方发生在轨道面交线附近。此外,空间目标的轨道受各种摄动力的影响,两目标之间的距离存在一定的振荡起伏,但整体接近距离随时间的变化有渐变的趋势,因此提出了一种附加时间窗的空间目标接近分析方法。结果表明,该方法能够对空间目标之间进行快速精确的接近分析,获得两个空间目标之间的最接近时刻和接近距离等参数,特别是针对全球碰撞预警分析,将有效减少计算时间,计算效率提升10%以上。
Without considering the coplanarity or nearly coplanarity of space targets,there exist an intersection line on the orbital planes of two space targets,and the possible intersection of two space targets occurs near the orbital intersection line.In addition,the orbit of space targets is affected by various perturbation forces,and the distance between two space targets has certain fluctuations,but the overall approach distance has a gradual trend when time changes.Therefore,a spatial target approach analysis method with additional time windows was proposed.The results show that this method can quickly and accurately analyze the approach between space targets,and obtain the parameters such as the closet approach time and approach distance between two space targets,especially for the global collision warning,which will effectively reduce the calculation time and improve computation efficiency by more than 10%.
