Abstract:

In a method for inferring the refractive index profile of the lower atmosphere a signal pattern comprising interference nulls is observed by receiving a signal from a satellite transmitter over a period of time. Hypothetical signal patterns are successively calculated by hypothesizing the validity of different refractive index profiles and compared with the observed signal pattern until one of them matches the observed signal pattern to within a selected limit of error.
