The use of the phase characteristics of two magnetoionic components of a radio signal in the problem of determining the spatial structure of medium-scale disturbances
Abstract
A method for determining the characteristics of medium-scale traveling disturbances (MSTDs) is proposed which is based on an analysis of the time variations of the Doppler shifts and arrival angles of two magnetoionic components of a radio signal reflected in the F2-region. It is shown that, in the presence of the vertical component of MSTD motion, a time delay arises between the fluctuations of Doppler frequencies of different magnetoionic components, which provides information about the full vector of the disturbance phase velocity. The application of the method is illustrated using experimental time series of Doppler frequencies and arrival angles of ordinary and extraordinary components of a radio signal measured on a 100-km radio path.
