EXPERIMENTAL OBSERVATIONS OF FORWARD SCATTERING OF LIGHT IN THE LOWER ATMOSPHERE

Abstract

The report deals in part with the experimental results from seven measurements on the forward scattering of light by the atmospheric aerosol. In addition, considerations of the problem of detecting forward scattered light in the daytime show that estimated results agree with the available experimental data. Considerations of the feasibility of using over-the-horizon propagation as a communications link leads to the estimation that communication between fixed points at Morse code rates is currently feasible over ranges of the order of 50 km in the daytime for meteorological ranges of 16 km or more, using a narrow-beam projector as source. Ship-to-ship communication would require sources of very high power or precise stabilization and pointing of existing high-intensity searchlight sources.
