Paper Abstract

To eliminate the communications blackout phenomenon of reentry vehicle during reentry, characters of the communications channel of plasma sheath is studied. And based on the electron density and temperature of the sheath, the transmission model of optical signal in plasma sheath is formed. Making use of the light transmission model in plasma sheath to do simulation and calculation, the refraction and attenuation state can be got. It illustrates that the influence of sheath to the transmission of optical signal is limited, and demonstrates the theoretical feasibility of light communications in reentry communications.
