Predstavleny rezultaty modelirovanija ionosfernogo alfvenovskogo rezonatora (IAR) i sravnenije rezultatov prochoždenija elektromagnitnych voln čerez IAR k zemnoj poverchnosti s dinamičeskim spektrom odnovremennych nabljudenij spektralnych rezonansnych struktur (SRS). Dlja modelirovanij IAR byli ispolzovany parametry ionosfery, polučennyje po izmerenijam programmy CP-1 skandinavskogo radara EISCAT. Na osnove postrojennoj modeli IAR byli vyčislenny koefficienty otraženija RC(f) i prochoždenija TC(f) elektromagnitnych voln v častotnoj oblasti 0-5 Gc. Nabljudajemyje dinamičeskije spektrogrammy SRS sostojat iz spektralnych linij, u kotorych uverenno opredeljajutsja častoty, vremennyje variaciji častot i rasstojanija meždu sosednimi rezonansnymi linijami. Vyčislennyje častoty maksimumov koefficienta prochoždenija signalov TC k zemnoj poverchnosti sootvetstvujut nabljudajemym častotam dinamičeskogo spektra SRS.

We present the results of modeling of the ionospheric Alfven resonator (IAR) and compare the results of electromagnetic waves passing through IAR to Earth's surface with the dynamic spectrum of simultaneous observations of spectral resonance structures (SRS). IAR is simulated using ionospheric parameters obtained from measurements made with the CP-1 program of the Scandinavian EISCAT radar. The IAR model is employed to calculate coefficients of reflection RC(f) and transmission TC(f) of electromagnetic waves in the frequency range 0-5 Hz. The observed dynamic SRS spectrograms consist of spectral lines, in which frequencies, time variations of frequencies, and distances between adjacent resonant lines are confidently determined. The calculated frequencies of maxima of the signal transmission coefficient TC to Earth's surface correspond to the observed frequencies of the dynamic spectrum of SRS.
