Fourier Analysis of Radio Bursts Observed with Very High Time Resolution
Original language description
We analyze the power-spectrum parameters and variability for two millisecond radio dm-spike events and one drifting pulsation structure (DPS) event, for which the structures of the recorded signals were analyzed with an effective time resolution of 0.0008 s in five adjacent frequency bands of their radio spectra. We found that Fourier spectral indices varied rapidly when radio fine structures were recorded. Otherwise they remained close to zero, indicating the presence of noise. For the 10 -aEuro partsper thousand 40 Hz frequency interval of the power spectra the mean values of the Fourier spectral indices varied up to -1.51 for the dm-spikes and up to -1.53 for the DPS event. Cross-correlation coefficients of radio fluxes in adjacent frequency bandsvaried between 0.12 and 0.60 for dm-spikes and between 0.77 and 0.94 for the DPS event. The shortest fine structure found in the studied events lasted 0.001 s. These results are entirely new for dm-radio spikes and confirm a single previo
