Solar sporadic radio emission in the decametre waveband
Abstract:The first results of observations of solar sporadic radio emission with the UTR-2 radio telescope in 2001–2003 are reported in this paper. Using new back-end facilities, the digital spectro-polarimeter and 60-channel spectrometer allowed us to obtain data with a time resolution up to 2 ms and a frequency resolution of 12 kHz in a continuous frequency band of 12 MHz. The usual type III bursts, type IIIb bursts, U and J bursts, spikes and unusual bursts in the decametre wavelength band are discussed in this paper. Special attention is paid to the detection and analysis of type II bursts and their properties, the fine structure of type III bursts, the new observational features of drift pair bursts, ‘absorption' bursts and the statistical analysis of solar radio bursts.
