GEOPHYSICAL FACTOR OF EFFECTIVENESS ON IONOSPHERE
For data transfer to vessels in high latitudes decametric communication channels are widely used. For increasing their efficiency the mechanism of waveguide ionospheric propagation can be used. Realisation of this mechanism is possible through the creation of artificial ionosphere irregularities under active influence of powerful short-wave radiation on it. Owing to small, in comparison with natural processes, energy effects, it is necessary to consider heliogeophysical conditions which are dynamic. Based on the analysis of experiments conducted in October-November of 2017 on high-power heating facility in Tromso, the attempt is made to estimate the possibility of using high-power heating technologies for forming the conditions of waveguide propagation of decametric waves in the ionosphere. With that for the first time potentialities of software defined radio are used.
