Dynamic Spectra

In order to study the wide band structure of the Jovian decametric radio emission, the University of Florida operates a broadband radio spectrograph. The spectrograph covers the frequency range from 18 to 36 MHz and uses the conical log spiral array.

The following examples of dynamic spectra show the complex structure of the emission. Some of the most common types of structure include modulation lanes, scintillation, and other types of drifting structures of unknown origin. For plotting the dynamic spectra, the intensity of the emission has been color-coded with blue representing the smallest and red the largest intensity.

Examples of wide band dynamic spectra of Jovian decametric radio emission are shown below.
