Estimation of optimal wavelengths for atmospheric non-line-of-sight optical communication in the UV range of the spectrum in daytime and at night for baseline distances from 50 m to 50 km.

For implementation of non-line-of-sight optical communication, the wavelength from the range 200-400 nm at which the signal-to-noise ratio reaches a maximum depending on the baseline distance is estimated. The estimates are performed in the daytime, at moonlit night, and without background radiation. The results obtained allow us to recommend
