| Abstract: | The problem of short-wave radio-signal reflection from a parabolic ionospheric layer with traveling ionospheric disturbances (TID) in the form of density waves is solved in an approximation of geometrical optics. Formulas that relate the arrival angle and Doppler shift of a radio signal to the TID parameters are derived by the small-perturbation method for the characteristic function. The inverse problem of determination of the TID spectral characteristics is solved. The amplitude, dispersion law, and propagation direction of ionospheric irregularitiesare restored. |
