Abstract
The goal is to study parameters of drifting type III bursts, and find out the emission mechanism of these bursts and understand what factors affect instantaneous spectral bandwidth of these bursts. We used simultaneous observations of microwave type III bursts with high temporal, spatial and spectral resolution from the Siberian Solar Radio Telescope (5.7 GHz, 14 ms resolution) and from the spectropolarimeters (5.2–7.6 GHz, 5 ms) of the National Astronomical Observatories. Characteristic parameters such as starting frequency, total and instantaneous bandwidth, polarization degree, total duration, and rate of frequency drift were determined for the radio bursts. We analyzed and estimated parameters, which determine instantaneous bandwidth.
