Proposed satellite techniques for performing a high resolution survey of the radio sky at medium wavelengths

The reception pattern of a short dipole above the F layer is considerably modified by refraction in the ionized medium and has the form of a cone with sharply bounded edges modulated by a fine interference pattern. The properties of this reception pattern are discussed and suggestions are made for satellite experiments based on this phenomenon. It is shown that a variety of techniques are available to give resolving powers of any desired value down to a fraction of a degree.
