Abstract
The plasma sheath around the hypersonic vehicle is affected by the turbulence. Random changes in electron density disrupt magnitude of electromagnetic wave so that communication quality become worse. This paper focuses on the statistics of the electron density, and statistical models of electromagnetic wave amplitude at Ka band is obtained by the electromagnetic calculation. Finally, the influence of electron density and radio frequency on the mean and variance of transmission coefficient is studied. The results show that, with the increase of the electron density, the amplitude of the transmission coefficient decreases, and the variance increases. With the increase of the frequency of the radio wave, the amplitude of the mean is increasing and the variance is decreasing.
