再入飞船通信环境建模研究

Modeling of communication environment of reentry spacecraft

  • 摘要: 再入飞船的通信环境所受影响主要体现于飞船周围等离子体鞘对电磁波产生衰减。为了研究飞船再入过程中衰减对通信的影响,需要建立飞船外围的三维通信衰减仿真模型,在此基础上可以研究适用于再入通信环境的新型通信技术。为此文章提出了再入飞船通信衰减的动态建模方法,并根据气动、热力学和电磁波理论公式提出了具体的飞船再入动态通信环境建模方案,同时阐述了各部分建模的研究方法,为进一步研究应对黑障的新型通信技术奠定了基础。
    Abstract: The main feature of a reentry spacecraft communication environment is the attenuation of electromagnetic waves caused by the plasma sheath around the spacecraft. To study the attenuation impact on the communication of a reentry spacecraft, a three-dimensional simulation model should be built, which can be used to study new type communication technologies. In this paper, a method of modeling dynamical three-dimensional communication attenuation is proposed by using aerodynamics, thermodynamics and electromagnetic theorems. The modeling method of each module is discussed, as the fundamental of further research on blackout countermeasure technologies.
