Automated detection of Sun decametre radio bursts by the radio telescope URAN-3

The problem of the automated determination of the parameters of the sporadic decameter radio emission of the Sun with help of the radio-telescope URAN-3 taking into account its functions in the Ukrainian VLBI URAN structure is analyzed. An overview of alternative solutions of the problem is carried out. The technology of searching and detecting the radio bursts of type II and determination of such parameters as speed of drift in frequency sub bands, intensity, and duration and frequency width of bursts for a number of selected frequencies are considered. The effectiveness of the developed technology is confirmed by the results of long-term radioastronomical observations carried out at the URAN-3 radio telescope in 2011–2017. The formed on the basis of obtained and accumulated experimental data multiparameter relative database of solar activity is intended for further studies of the relation between the helio- and the geophysical phenomena for the purpose of developing forecasting models of geophysical manifestations of solar activity and evaluating the “geoefficiency” of active solar processes.
