Review of theory of interplanetary and interstellar scintillation

Basic theoretical methods and solutions describing radio wave propagation in the turbulent plasma are briefly reviewed. Consideration is given to the results on scattering effects such as angular scattering, pulse broadening and spectral line spread. Also treated are phase and frequency fluctuations. Of particular concern are problems of the correlation theory of intensity fluctuations for weak and strong diffractive and refractive scintillations. Special attention is paid to the effect of refractive scintillation on a diffractive pattern.
