A method for determining the parameters of the thin turbulent structure of a large-scale ionospheric irregularity from the trajectory characteristics of decametre radio signals emitted from the spacecraft is proposed. The spatial parameters of large-scale heterogeneity are determined by the results of numerical synthesis of the distance-frequency characteristics of radio signals. The statistical moments of signals’ trajectory characteristics at various operating frequencies, obtained by analytically solving stochastic ray equations, are used to diagnose the thin structure of the irregularity.
