The weighting function for scintillation on a folded path
weightingfunctio00anby.pdf (3.144Mb)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.
