Abstract:

The possibility that atmospheric turbulence clear air turbulence can cause extended propagation beyond the optical line of sight is examined. It is possible for a distant transmitter to interfere with a receiver via scattering from atmospheric turbulence, but it is not likely that a radar will receive distant ground echo via scattering from turbulence. From a compilation of published data it is shown that the structure constant of the atmosphere a measure of scattering is a function of altitude with an apparent maximum in the vicinity of 500 to 1000 m.
