Satellite-aerial communication (SAC) is the most necessary and reliable way to bridge the aerial terminals with their remote command and control center when terrestrial relay infrastructure is unavailable. However, as an inescapable obstacle, adjacent space interference from neighboring satellites unavoidably leads to the loss of the performance of SACs. To uncover the impacts of space interference, in this paper, a SAC system including a satellite (S), an aerial platform (D), and a space interference (I) is considered. Specifically, S operates in a circular orbit and I, which is randomly distributed in the neighboring space around S, produces a jamming signal to interfere with the information delivery between S and D. Considering the randomness of S and I and employing geometric probability theory, an approximate and asymptotic outage probabilities of the considered SAC system are studied. Moreover, the multi-interference scenario is investigated accordingly. Finally, numerical results are presented to validate our proposed analysis and some insightful conclusions are achieved to reveal the effects of spatially random space interference on SAC.

空间随机空间干扰对星空下行传输的影响


当地面中继基础设施不可用时，卫星空中通信（SAC）是连接空中终端与其远程指挥和控制中心的最必要和最可靠的方式。然而，作为不可避免的障碍，来自邻近卫星的邻近空间干扰不可避免地导致SAC性能的损失。为了揭示空间干扰的影响，本文考虑了包括卫星（S）、空中平台（D）和空间干扰（I）的SAC系统。具体来说，S在圆形轨道上运行，I随机分布在S周围的邻近空间中，产生干扰信号，干扰S和D之间的信息传递。考虑到S和I的随机性，采用几何概率理论，研究了所考虑的 SAC 系统的近似和渐近中断概率。此外，还相应地研究了多干扰场景。最后，给出了数值结果来验证我们提出的分析，并得出一些富有洞察力的结论来揭示空间随机空间干扰对 SAC 的影响。
