Spectral processing of oblique ionospheric souniding signals using parametric methods

We, compare the efficiencies of some parametric methods of spectral evaluation in regard to the problem of analysis of ionospheric sounding signals, using model calculations and actual signal realizations. The use of Kulikov’s method for spectral processing is described. The efficiency of this method for determining the mode structure of ionospheric signals is shown. A criterion for choosing the model’s order in this method is proposed.
