Developments in the use of a rotating interferometer for measurements of bearing and elevation angles, for determination of the vertical and horizontal spreads in the power in the incoming cone of rays, and for determination of the correlation between these, are described. It is shown that, using an auxiliary fixed remote antenna, a very simple method of measuring the coherence ratio, i.e., deriving the value of the specular component, is possible.
