摘要	The scattering and absorption caused by sand-dust channel will lead to serious attenuation of the laser signals. By considering the characteristics of the sand-dust particle radius distribution and the effects of sand-dust moisture content, the impact of sand-dust on the attenuation characteristics of laser signal is investigated and the expression of signal-to-noise ratio at the receiving end is proposed. Moreover, the bit error rate and channel capacity under sand-dust weather are deduced for the OOK modulation. Furthermore, the effects of atmospheric visibility, transmission distance, sand-dust moisture content and laser wavelength on the bit error rate and channel capacity are simulated. The results show that the channel capacity and system BER performance decrease with the increase of sand-dust moisture content, transmission distance and the decrease of atmospheric visibility. When the atmospheric visibility is 4 km, the system bit error rate achieves 10-2 orders of magnitude with a wavelength of 1 550 nm and a transmission distance of 1 km and the normalized channel capacity is up to 8.48 bps/Hz. © 2019, Science Press.
