Usage of regularization techniques for effective electron collision frequency determination from oblique ionospheric sounding

P. F. Denisenko, N. V. Nastasyina, and V. I. Vodolazkin P. F. Denisenko et al.

Abstract. Computer modelling is used to investigate the possibility of determining ionospheric parameters from slightly oblique ionospheric soundings, using absorption data for decametric radio waves of different polarization. It is shown that with mean square measurement errors of 0.5 dB, and using regularization algorithms to solve the inverse problems, electron collision frequency profiles can be obtained for the night F-region with errors of less than 30%. Both temperatures of electrons and neutrals are also determined to within 10%.
