A new method of space exploration by radar, using incoherent scattering

Incoherent scattering is discussed in the context of the phenomenon of scattering of radio waves by spatial fluctuations in electron density. A review is given of both theoretical and experimental results. Emphasis is placed on the ideas involved in measuring properties of the upper ionosphere, such as the electron density, temperature, electron drifts, and the strength and direction of the magnetic field.
