Space Radio Science deals with the theory and practice of space communications with Earth's satellites and interplanetary probes, interstellar radio communications in our galaxy, and the effects of gravitational fields on propagating radio waves. The text describes a method of radio occultation used to monitor planetary atmosphere and ionosphere. The author considers remote sensing of circumsolar and interplanetary plasmas, as well as of the Earth and other planets in the solar system. The book provides a comprehensive analysis of radiophysical problems and methods, as well as the benefits of various spacecraft and radio signals. It looks at problems such as gravitational pull and its effect on the propagation of radio waves. This monograph is ideal for radio-physicists, engineers and students in space radiophysics, remote sensing, propagation of radio waves and space communications.
