Abstract. The dynamics of radio signal propagating through the single-hop vertical ionospheric path was analyzed using the experimental time series. Correlation dimension, Lyapunov exponents spectrum for signal and noise components are evaluated. Attractor reconstruction for the weakly disturbed ionosphere is carried out.
Key words: radio wave propagation, ionospheric communications channel, noise, phase surface, attractor.
