摘要
飞行器在临近空间高超音速飞行中可能出现的"黑障"现象对测控系统提出了巨大的挑战。在分析飞行器表面等离子的构成以及造成射频信号衰减因素的基础上,构建了射频通信"黑障"效应研究的总体框架,提炼了关键技术并给出解决方案与初步分析结果,可为相关试验提供参考与建议。
Frequency blackout problem is the major challenge of the near space hypersonic vehicle's radio frequency (RF) communication. In this paper, based on the analysis of plasma formation and signal attenuation, a research scheme of the radio frequency blackout problem is developed, and the key technology is presented.
