Obstacle Impact on the UV-Light Atmospheric Transmission Characteristics

Abstract

In order to further understand the transmission characteristics of UV-light signal, this paper, based on the algorithmic model of Monte Carlo method of UV-light non-line-of-sight transmission, conducts the simulation analysis of the obstacle impact on UV-light signal transmission characteristics in the atmosphere. The results show that due to the presence of obstacle, the blind region of detection appears; this blind region is related to the distance of the obstacle, as well as to transmission elevation angle, receiving elevation angle and obstacle height of obstacle. The obstacle exerts a slight influence on energy intensity, but just its height changes the range of blind region detection. The transmission elevation angle and the receiving elevation angle, in case of the presence or absence of the obstacle, have two energy distribution peaks which change to some extent, and the energy attenuation is more significant in case of the absence of the obstacle.
