摘要

为研究航天器再入过程中的测控“黑障”问题,文中建立非均匀等离子体模型,仿真分析了在不同再入高度下,信号测控频率变化对迎风面、背风面的传输情况的影响。结果表明:在航天器再入过程中,提高测控频率可改善信号在等离子体中的传输性能;电磁波在航天器背风面传输性能显著优于迎风面传输性能Ka-Band信号从背风面传输的透射率相比于迎风面至少提高88.3%,衰减值至少降低10dB,为中继法解决“黑障”问题提供数据参考。

Abstract

In order to study the measurement and control of black barrier during spacecraft reentry, non-uniform plasma model was established in this paper to simulate and analyze the influence of the change of signal measurement and control frequency on the transmission status of windward and leeward side at different reentry heights. The results showed that in the process of spacecraft reentry, the transmission performance of the signal in the plasma sheath could be improved by improving measurement and control frequency The transmission performance of electromagnetic wave on leeward side of spacecraft was significantly superior than which on windward side. The transmissivity of Ka-Band signal transmitted from the leeward side was at least 88.3% higher than which from the windward side, with decrease on the attenuation by at least 10 dB, and it provided data references for solving black barrier problems by adopting relay method.
