当飞行器以超高速在大气层中飞行时，由于气动加热或烧蚀，在飞行器周围会形成等离子体鞘套。这将影响飞行器的通信特性，严重时会使通信中断，从而威胁飞行器的安全。我国新一代航天航空飞行器在大气层中飞行的时间长、速度快，而且弹道复杂，需要实时通信和控制，因此需要彻底解决通信中断问题。针对新一代航天飞行器面临的通信中断问题，研究了利用天线位置和地面遥测设备的布站优化、毫米波和太赫兹波通信、外加强磁场和激光通信等方法解决黑障问题的可能性及存在的问题。

When a space vehicle is flying at ultra-high speed in the atmosphere, a plasma sheath may form around it due to aerodynamic heating or ablation. This will affect the communication characteristics of the space vehicle. Further, it will result in serious communication disruption and hence threaten the safety of the space vehicle. The new generation of space vehicles of our country will fly in the atmosphere for longer time at higher speed. Moreover, because of their complex trajectory,real-time communication and control are needed. Therefore, the problem of communication disruption should be solved thoroughly. The possibility of using the methods such as distribution optimization of antenna location and ground telemetry equipment, millimeter-wave and terahertz wave communication, external magnetic field and laser communication to solve blackout and the problems to be faced are studied.
