在探讨卫星振动对空间光通信系统误码率所产生的影响时,有必要分析不同振动类型的影响问题。为了使讨论简单,本文主要侧重对正弦振动进行分析。分析结果表明,当振动持续时间为整周期时,误码率仅为振幅的函数,此时误码率随振幅的增加迅速上升,而与振动频率无关;当振动持续时间为非整周期时,误码率随时间的增加而波动,波动的起伏逐渐减小,误码率趋于仅与振幅有关的常数。该项工作为今后研究卫星复杂振动对空间光通信的影响打下了基础,同时也为研究对卫星振动影响的补偿分析提供了有意义的参考
In discussing the impact of satellite vibration on the bit error rate of space optical communication systems, it is necessary to analyze the impact of different vibration types. In order to make the discussion simple, this article focuses on the analysis of sinusoidal vibration. The results show that when the duration of the vibration is the whole period, the bit error rate is only a function of the amplitude. At this moment, the bit error rate increases rapidly with the increase of the amplitude but has nothing to do with the vibration frequency. When the duration of the vibration is the non-integer period, The bit error rate fluctuates with the increase of time, the fluctuation undulates gradually and the bit error rate tends to the constant related only to the amplitude. This work lays the foundation for studying the influence of complex vibration of satellite on space optical communication in the future and also provides a meaningful reference for studying the compensation analysis of satellite vibration effects
