Resumo

Results of simulations of the pulse response of an atmospheric optical communication channel on scattered radiation at wavelengths of 0.3, 0.5, and 0.9 μm are considered. The performed analysis shows that the maximum power of the received information signal at base distances of 2–3 km and less between the source and receiving system is reached at λ = 0.3 μm; for longer base distances and low turbidity of the atmosphere, λ = 0.5 μm. The highest maximum power is observed at λ = 0.5 μm under high turbidity of the atmosphere and base distances of 3–10 km. However, if the base distances are longer than 10 km, the maximum of the information signal power is reached at λ = 0.9 μm. For an example of a laser source and receiving system, using calculation results for the pulse reaction of the atmospheric communication channel at λ = 0.5 μm, we estimate the limiting base distance between the source and receiver, as well as the limiting pulse frequency which is not filtered by the communication channel.
