Propagation effects in disturbed environments

Radio beacon diagnostics are still the least expensive means of obtaining data on naturally occurring and artificially induced striations. To exploit this capability fully, we develop the theory for interpreting rocket-beacon data when the velocity component along the line of sight to the receiver is much larger than the transverse component. A simple and direct relationship is shown to exist between the beacon-phase spectrum and the one dimensional in-situ spectrum that does not involve any unknown parameters, such as the path length within the disturbance. A model is also developed for computing the Doppler spectrum for the usual situation in which the transverse velocity component dominates.
