An Investigation of Atmospheric Optically Scattered Non-Line-of-Sight Communication Links

Abstract

This report discusses the work performed in the second year of a two year program to investigate short-haul non-line-of-sight optical scatter communication links. The wavelength region considered for this study is the middle ultraviolet (uv) (2000 A - 3000 A). This region is attractive for communication purposes because the absence of solar background radiation makes wide-angle receivers practical. Furthermore, the short wavelengths result in significant scatter from molecular atmospheric constituents (Rayleigh scatter), so that the availability of a non-line-of-sight link is extended into clear weather. The goal of the investigation has been to obtain a fundamental understanding of scatter propagation in low visibility atmospheric environments. In particular, the work has focused on the determination of parameters needed for optical communication system design, such as angular spread and multipath time spread.
