The Weighting Function for Scintillation on a Folded Path.

Abstract

In the case of a spherical beam wave propagating in a weakly inhomogeneous medium which has a Kolmogorov spectrum, Dr. Ze'evi derived a weighting function for scintillation for a direct and for a folded path with respect to the position of the turbulent medium. Experiments were performed to verify Ze'evi's weighting function for a folded path for three different types of reflectors. The experimental results did not support Dr. Ze'evi's theory. We found that the scintillation weighting functions are less weighted near the detector and have an unexpected increase near the reflector. These results are discussed by using a geometric optical model of the turbulence.
