Abstract:

In order to further understand the propagation characteristics of Ultraiolet signal in different atmospheric conditions, based on the ultraviolet NLOS(Non Line Sight) propagation Monte Carlo algorithm model. The ultraviolet signal propagation characteristics is simulated under different conditions in the atmospheric. The results showed that: single pulse signal with the increase of distance, pulse width and pulse delay is more obvious; under clear, cloudy, rain, fog of different weather conditions, the rain of the propagation signal energy attenuation is maximum.

Key words: Monte Carlo method, Ultraviolet(UV)-light simulation, characteristic of atmospheric propagation, impulse response function
