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 I p with the proton energy E p > 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 V mII and the relative difference between radio emission frequencies at the first two harmonics b. It is shown that the coefficient of correlation between I p and b increases with E p growing from 0.40 to 0.70, while a similar coefficient between I p and V mII does not exceed 0.30. Indications in favor of the two-stage SCR acceleration model are obtained.
