The aim of this work is a qualitative and quantitative study of the evolution of the characteristics of radio emission bursts from powerful proton and non-proton solar flares. Over the past few decades, experts have shown, based on data from numerous multi-wavelength studies of solar flare radiation, that eruptive solar flares accompanied by proton enhancements consist of an impulsive and a gradual phase. In the microwave range, valuable research devoted to the diagnostics of radio bursts of solar proton events based on their intensities is based on the IZMIRAN method. We also took a creative approach to solving these problems and for the first time applied the fractal method and its "sliding window" version to the time series we compiled, obtained from radio bursts of solar proton events observed simultaneously in the microwave ranges λ=10.7 and 27.8 cm. Observations were carried out in 2014÷20 on the RT-12 radio telescope of the Institute of Ionosphere of the Republic of Kazakhstan at frequencies f=1 and 3 GHz. In addition, three-proton events were observed in the microwave regions λ=10.7 and 27.8 cm from solar flares, satisfying the Tanaka-Enome criterion , similar to the criterion. Based on the values of and calculated by us for the period of time during which the events occurred, we can determine its maximum unstable periods.
