Spectrographic Investigations of the Structure of Jupiter's Decametric Radio Emission Sources
Abstract
A possibility to determine the structure of distributed sources of Jupiter's decametric radio emission using spectrographic studying of statistical characteristics of fluctuating planetary emission is analyzed. Observational conditions are determined when measurements of frequency spectra and frequency-temporal cross correlation function of intensity fluctuations can be used to determine spatial structure of Jupiter's decametric radio emission sources. Theoretical results are compared with known results of experimental investigations of statistical characteristics of Jupiter's decametric emission. Frequency non-stationarity of intensity fluctuations of emission received by spectrograph in a wide frequency band is emphasized. In particular, it is found that narrow band measurements of frequency-temporal cross correlation of intensity fluctuations of decametric radio emission could be used as effective diagnostic tool for determining weak spatial gradients of Jupiter's magnetic field.
