摘　　要：针对飞行器在穿越大气层途中,摩擦高温产生等离子体鞘套,中断与地面通信,阐述对飞行器的这一传输过程进行仿真建模,分析THz波在高温等离子体中的传播特性。主要通过研究碰撞频率(fen)、磁场强度(B)、厚度(d)、电子温度(Te)分析研究THz波在高温、磁化等离子体中传输特性,分析在高温等离子体中传播的透射值(T)以及衰减值(Att)。探讨几种参数对于缓解“黑障”出现的应对措施,保证飞行任务的顺利完成。In view of the fact that the aircraft rubs high temperature to generate plasma sheath and interrupts communication with the ground during its transit through the atmosphere,this paper describes the simulation modeling of this transmission process of the aircraft and analyzes the propagation characteristics of THz wave in high temperature plasma.The transmission characteristics of THz wave in high-temperature and magnetized plasma are mainly analyzed by studying the collision frequency(fen),magnetic field strength(b),thickness(d)and electron temperature(TE),and the transmission value(T)and attenuation value(ATT)of THz wave propagating in high-temperature plasma are analyzed.It explores the countermeasures of these parameters to alleviate the appearance of"black obstacles"and ensure the smooth completion of the flight mission.
