The report of scientific research project contains 152 pp. of typewritten text in 7 sections, 100 figures, 15 tables and the list of 67 references. Results of investigations on solar sporadic radio emission are presented in this work. Observations with help of Ukrainian radio telescope UTR-2, URAN-2, GURT in period of maximum solar activity of 24 cycle (2012-2016) gave a lot of new information concerning properties of such bursts as type III bursts, type II bursts, type IV bursts, S-bursts etc. New type of bursts such as behind-limb bursts, tadpoles, type III bursts with changing sign of drift rates were registered. Methods of determination of parameters (density, temperature, magnetic field, inhomogenuity sizes and others) coronal plasma, from which decameter radio emission of these bursts comes out, were proposed. A new research trend, radio seismology, which allows to find parameters of type IV sources associated with coronal mass ejections (CME), was formulated. Observations of CS(J=2-1) lines at frequencies 6.7 and 12.2 GHz from 124 sources were carried out in the mm radio astronomy field. Their parameters and places were found. It was shown that correlations between methanol masers intensities and CS(J=2-1) line intensities of these objects higher that with bolometric infrared intensities.
