IR Attenuation Estimation in a Free-Space Environment with Sand and Dust Particles

An approach for estimating the attenuation constant of propagation in a sandstorm at a wavelength of 1550 nm with various prevailing visibility is described in this study. An adequate dust particle size, distribution statistics, and generalized Mie scattering theory were used in the estimation. The visibility is calculated using the computed attenuation at a wavelength of 550 nm. The findings are compared to the measured data found in the literature. To regale, a detailed sensitivity analysis for various sandstorm structures is presented. This analysis is used to signalize a dusty channel in order to simulate a single input-output 1550 nm free space optical link. By computing the bit error rate of the system, the performance of the optical link in flurry dust with attenuation smaller than 10 dB/km is investigated.
