Abstract

Free-space optical communication (FSOC) is used to transmit a modulated beam of light through the atmosphere for broadband applications. In recent years, FSOC has played an increasingly important role in providing broadband wireless communications. Fundamental limitations of FSOC arise from the environment through which light propagates. The light signals (photons) transmitted through the battlefield environment will interact with particles of smoke, dust and sand along the propagation path. Photon-particle interaction causes dispersion of the light signals, which has significant effects on signal attenuation. This paper addresses transmitted light signal dispersion (spatial, angular and temporal dispersion) for FSOC operating in a battlefield environment. Correlation between spatial and angular dispersion of the received light signals is investigated. Based on the properties of correlation, for a fog oil type of medium, a receiver with a small field-of-view (FOV) is proposed to receive the communications signal.
