Interplanetary Scintillation and its Relation to the Angular Structure of Radio Sources

Abstract

The recent discovery of interplanetary scintillation has provided a new technique for deriving inforrnation about the angular structure of radio sources in the range 0″.1−1″. A full account is given of the theory of the method and its practical application. The possibilities of the technique are illustrated by some typical observations at a frequency of 178 Mc/s.
