PROGRESS IN THE STUDY OF DECAMETER-WAVELENGTH SOLAR RADIO EMISSION WITH UKRAINIAN RADIO TELESCOPES. Part 1. (Invited paper)

Subject and Purpose. Results are presented of the solar corona investigations performed with world famous Ukrainian radio telescopes. The work has been aimed at offering a consistent review recent achievements in observations variety low-frequency emissions from Sun. Methods Methodology. studies quiet (thermal) sporadic (burst-like) Sun have car- ried out decameter-wavelength telescopes UTR-2, GURT URAN-2. Specific features sources presented, characterization optimized techniques that were applied each case for evaluating physical parameters areas wave generation. Results. analysis temporal, frequency spatial characteristics allowed suggesting number models coronal electron density distribution, magnetic field strengths corona. Also, our experimental results proven to be observational data obtained different ranges use both ground based space-borne instruments. Conclusions. permitted studying, high fre- quency resolutions, various localized sources. Along large effective area sensitivity antennas, this permits application wide range methods tools detecting analyzing bursts, strong weak intensity, against background terrestrial interference natural or artificial origin
