The numerical simulation method and the transport of the communication characteristics for different electromagnetic waves of the plasma sheath are analyzed. Firstly, based on the flight communication data of a blunt-nosed project, the numerical simulation method and the transport method of the communication characteristics in this paper are preliminarily proved to be feasible. Secondly, the communication characteristics of the plasma sheath for the lifting reentry vehicle are obtained in the typical trajectory. The transport of the communication characteristics for the S-band signals, Ka-band signals and K-band signals are also investigated, which indicates that the high-frequency signals will improve the communication characteristics and can be an effective technical approach for solving the communication blackout based on the domestic relay method. Finally, the influences on the transport of the communication characteristics of the direction angle and the angle of attack are investigated. The results can provide a reference for the communication design of the reentry vehicles to solve the communication blackout in China. [ABSTRACT FROM AUTHOR]
