PECULIARITIES IN THE IONOSPHERIC SCINTILLATION SPECTRAL INDEX BEHAVIOR BY OBSERVATIONS OF THE COSMIC RADIO SOURCES AT THE DECAMETER WAVELENGTHS

Radio Physics and Radio Astronomy, 2019
Purpose: With relation to radio astronomy, ionospheric scintillation of discrete cosmic radio sources is an undesirable effect. At the same time, ionospheric scintillations carry information on the ionospheric turbulence and are a separate object of ...

Solar system radio emissions studies with the largest low-frequency radio telescopes

, 2014
We describe the trends and tasks in the field of lowfrequency studies of radio emission from the Solar system's objects. The world's largest decameter radio telescopes UTR-2 and URAN have a unique combination of sensitivity and time/frequency resolution parameters, providing the capability of the most detailed studies of various types of solar and ...
