The theoretically multiple scattering model was based on probabilistic theory and stochastically migrating theory. The relationship between transmission loss and visibility was analyzed in different communication distance in radiation fog weather with Monte Carlo simulation. The results demonstrate that there is a visibility that can makes transmission loss lower when the communication range, the elevation angle, the transmitting beam-width divergence and the field-of-view (FOV) are determined.

Laser Diode (LD) with wavelength 808 nm was chosen as the source light of simulation.

Abstract: The theoretically multiple scattering model was based on probabilistic theory and stochastically migrating theory. The relationship between transmission loss and visibility was analyzed in different communication distance in radiation fog weather with Monte Carlo simulation. The results demonstrate that there is a visibility that can makes transmission loss lower when the communication range, the elevation angle, the transmitting beam-width divergence and the field-of-view (FOV) are determined. Various parameters of schematic diagram of the atmosphere laser scattering communication geometric framework can affect transmission loss of link for non-line-of-sight atmospheric scattering communication when the communication range and the visibility are determined and an optimized link for non-line-of-sight atmospheric scattering communication was put forward through the model simulation.
