Abstract: In the experiments of laser signal transport in rain medium, it is obvious that the
transmission in heavy rain is bigger than that in light rain. This shows that the attenuation of light
signal in light rain is bigger than that in heavy rain. The transmission attenuation of wireless laser
communication in rain is noticeable. According to the theory of Mie and Weibull raindrop
spectrum, the effects of the particle scales on laser scattering and attenuation efficiency factor
are analyzed, and the attenuation formula of the light wave of a single particle is deduced. The
definite equations between the attenuation and the rainfall ratio are obtained. The result shows
that scattering intensity of particle in heavy rain is bigger than that in light rain in forward
direction, and the forward scattering intensity increases. When laser signal transmits through rain,
attenuation coefficient in light rain is big, while it is small in moderate rain and heavy rain, and
increases in rainstorm. This result coincides with the facts. Attenuation characteristic of laser in
rain provides theoretical basis for laser applied in the communication system working in the rain.
