Communication with Hypersonic Vehicles via Nonlinear Plasma Processes

Abstract

We wish to transmit messages to and from a hypersonic vehicle around which a plasma sheath has formed. For long distance transmission, the signal carrying these messages must be necessarily low frequency, typically 2 GHz, to which the plasma sheath is opaque. The idea is to use the plasma properties to make the plasma sheath appear transparent. Numerical and analytical results show that it is possible to use proposed technique to receive GPS signal on the vehicle even using klystrons available on the open market. Transmission of the signal to the earth-based stations is also solved problem.
