Abstract : Identi iers: Troposphere. Methods are discussed by which the index of refraction profile along some path in the atmosphere could be determined through physical measurements made external to the path. In particular, the problem i that of determining the characteristics of a scatterer from the characteristics of the scattered signal. The Schrodinger equation is considered. From a knowledge of the reflection oefficient associated with a wave incident, it is shown how the scattering potential can be calculated. Next, the wave equation is studied. It is shown that the index of refraction profile can be determined from a knowledge of the scattering potential. (Author)
