Abstract : We developed useful results in connection with the use of nonlinear plasma properties to enhance communication properties and improve drag reduction and flight characteristics of hypersonic vehicles. Over the past three years, we carried out a detailed Investigation of the relevant plasma processes, such as Raman and Brillouin scattering, Ion-acoustic pluses and fast electrons. The objective of this work was to find under what parameters of plasma and microwave these processes could be effective for transmitting a message written on the signal wave to the vehicle through the plasma sheath.
