Abstract

The increasing reliance on photonic technologies for aerospace communication systems necessitates a deeper understanding of their behavior in space radiation environments. This paper investigates the radiation impacts on both analog and digital optical link architectures, assessing their vulnerability to transient faults, error rates, and cumulative degradation in high-radiation environments. The study employs analytical modeling and recent empirical data to evaluate the performance of digital and analog links under varying radiation conditions. For digital links, a bit error ratio (BER) analysis is conducted, while for analog links a signal-to-interference-plus-noise ratio (SINR) framework is applied. The results are consistent with prior architectural trade assessments for terrestrial and atmospheric applications, with digital links providing increased performance but requiring increased implementation complexity.

空间光子学：辐射对光链路设计的影响

航空航天通信系统对光子技术的依赖日益增加，需要对其在空间辐射环境中的行为有更深入的了解。本文研究了辐射对模拟和数字光链路架构的影响，评估了它们在高辐射环境中对瞬态故障、错误率和累积退化的脆弱性。该研究采用分析建模和最新的经验数据来评估不同辐射条件下数字和模拟链路的性能。对于数字链路，进行误码率（BER）分析，而对于模拟链路，采用信噪比（SINR）框架。结果与先前对地面和大气应用的建筑贸易评估一致，数字链接提供了更高的性能，但需要增加实施的复杂性。
