Abstract On the basis of data, obtained by means of the ground-based solar service RSTN (Radio Solar Telescope Network) and the geostationary satellite system GOES, the relationship between the solar cosmic rays (SCR) intensity Ip with the proton energy Ep > 1 MeV and parameters of meter-decameter type II radio bursts in the frequency range of 25–180 MHz is studied. The process of proton acceleration by shock waves was characterized by the frequency drift velocity of radio bursts VmII and the relative difference between radio emission frequencies at the first two harmonics b. It is shown that the coefficient of correlation between Ip and b increases with Ep growing from 0.40 to 0.70, while a similar coefficient between Ip and VmII does not exceed 0.30. Indications in favor of the two-stage SCR acceleration model are obtained.
