Abstract:

Measurements of optical propagation over-the-horizon caused by scattering from normal marine atmospheric aerosols have been made at range of 40 miles. Path loss, scattered beam angular distributions, and pulse distortion have been measured both at 1.06 micrometers and in the blue-green. Except for anomalies in expected forward scatter function, the results are in reasonable agreement with the propagation model. Based upon results of the propagation model and experimental results, communications system performance is determined using existing components. Design and construction of a one-way communication link between NELC and San Clemente Island 128 km are in progress.
