Characterization of ultraviolet communication in a mixed aerosol environment

Abstract

Wireless ultraviolet (UV) has strong scattering characteristics and can communicate through non-direct vision. When UV signals are transmitted in the atmosphere, they are affected by the absorption and scattering effects of atmospheric particles and atmospheric turbulence, resulting in attenuation of UV signal energy and reduced reliability of the communication system. This paper focuses on the channel model of UV non-direct-view single scattering communication, and simulates and analyzes the communication characteristics of UV light in atmospheric turbulence and mixed aerosol environment under horizontal, vertical and oblique range communication scenarios. The results show that at equal relative humidity, the wireless UV non-directive scattering communication performance for vertical communication scenarios is more affected by the mixed aerosol environment and the communication performance is worse.
