Abstract

In the observation of laser signal transmission in the rain, the attenuation ratio with the change of the size of the raindrops, the smaller the smaller the attenuation. In Mie scattering theory, with Weibull distribution model of raindrop size distribution and calculate the laser beam transmission in the rain attenuation characteristics in rainfall and changes with the distance, in Mie scattering theory, with Webb distribution model of raindrop size distribution, calculation of laser beam in the transmission of the rain attenuation characteristics in rainfall and changes with the distance. In the process of propagation, only the scattering attenuation of raindrops is considered, and the influence of diffraction and geometrical scattering is also considered. This explains the observed phenomena in the experiment, the attenuation of the laser signal in the light rain is larger than that in the heavy rain.
