摘要
自由空间紫外光非视距通信具有隐蔽、安全、高效的特性。本文根据Mie散射理论在Matlab环境下对紫外光非视距大气信道进行了模拟,分析了典型参数大气粒子对紫外光通信散射效率因子和特征图像的影响。模拟结果表明,大气粒子尺寸越大,紫外光散射的方向性越强;粒子的折射率越大,吸收作用越明显,紫外光散射的方向性越弱。本文的模拟结果为紫外光非视距通信系统的进一步发展提供了借鉴。
The free-space ultraviolet non-line-of-sight communication system has become a hot research topic in the field of military for its safety and efficiency. According to the classic Mie scattering theory, a model of Mie scattering of aerosol is built in this paper. The influence of aerosol on the signal features and the scattering efficiency factor are also analyzed. A reference for the further development of the UV non-line-of-sight communications system is provided in this paper.
