Abstract:

The investigation was concerned with the refractive index of electromagnetic microwaves coming from a space vehicle in an environment where this index equals unity. Originally, this effort was planned to be a continuation of an earlier effort to merely give the results of the computations for higher altitudes of the observation sites. However, the results obtained with the primary accepted assumptions for the approximation of the refractive index versus altitude showed them to be physically unrealistic, and therefore some modifications had to be made. These modifications, which do not invalidate the conclusions drawn in the earlier effort, are discussed in some detail. The results of the new computations are given and are compared with a long series of astronomical measurements. Author
