论文摘要
了解抗卫星测试产生的碎屑云的运动可以帮助我们了解这些测试的危险。这项研究介绍了Cesterak观察到的57个片段的轨道状态,并在印度反卫星测试的NORAD两行元素集中呈现。这些观察到的片段中有10个具有大于1000.0km的座椅的高度,最大的碎片为1725.7公里。我们还计算了碎屑数量,结果表明,直径大于0.2m的碎屑数量为14,直径大于0.01m的碎屑数为6587,并且直径大于0.001m的碎屑数为7.22e+5。碎片的二次碰撞结果将在该空间中产生更多的碎片。碎片的寿命取决于初始轨道参数和碎屑的尺寸。
Understanding the motion of debris cloud produced by the anti-satellite test can help us to know the danger of these tests. This study presents the orbit status of 57 fragments observed by the CelesTrak and presented in the NORAD Two-Line Element Sets of India Anti-Satellite Test. There are 10 of these observed fragments have altitudes of the apogee larger than 1000.0km, the maximum one is 1725.7km. We also numerical calculated the number of debris, the results show that the number of debris with the diameter larger than 0.2m is 14, the number of debris with the diameter larger than 0.01m is 6587, and the number of debris with the diameter larger than 0.001m is 7.22e+5. The results of the secondary collision of the debris will produced more fragments in the space. The life time of the fragments depends on the initial orbit parameters and the sizes of the debris.
