针对飞行器重返大气层时经历黑障区而导致的测控中断问题,对黑障产生的原因进行阐述,通过分析电磁波在等离子体中的传输特性和不同频率电磁波对信号传输影响,探讨航天测控中使用更高频率可以大大降低信号传输损耗,解决黑障区测控中断难题。并指出下一步需要在黑障区等离子体模型、电磁波在电离层及等离子体内的传输修正、如何克服降雨对链路衰减影响等方面进行深入的分析研究。

In view of disruption caused by spacecraft reentering into the atmosphere and experiencing the black area, the cause of the black-out was described. Through analysis of the propagation characteristic of the electromagnetic wave in plasma that affects different frequencies of radio waves to transmit, the higher frequency band applied to space TT&C to resolve the problem of the spacecraft communication discontinuity in the blackout area was discussed. It's indicated that the plasma model of the blackout area, correction of the electromagnetic wave propagation in plasma, how to overcome the effect of rain on transmission attenuation and so on should be analyzed and researched further.
