International Series of Monographs in Natural Philosophy, Volume 25: Radio Emission of the Sun and Planets presents the origin of the radio emission of the planets. This book examines the outstanding triumphs achieved by radio astronomy of the solar system. Comprised of 10 chapters, this volume begins with an overview of the physical conditions in the upper layers of the Sun, the Moon, and the planets. This text then examines the three characteristics of radio emission, namely, the frequency spectrum, the polarization, and the angular spectrum. Other chapters consider the measurements of the intensity of the solar radio emission, which indicate the existence of a lower limit. This book discusses as well the complex phenomena of the sporadic solar radio emission. The final chapter deals with the theory of the radio emission of Venus. This monograph is a valuable resource for radio astronomers and astrophysicists who are interested in the state of investigations in galactic radio astronomy.
