Abstract
Atmospheric and underwater optical communication lines have much in common due to variable conditions for the transmission of laser radiation along the path of the communication line, both in time and in space. The passage of a laser beam through a cloudy medium is accompanied by a decrease in the radiation intensity and an increase in the intensity of the scattered flux, which forms illumination, the intensity of which decreases with distance from the laser beam. As a rule, at the scales of distances at which the radiation of the optical range decays by several orders of magnitude, water in natural systems is homogeneous. The analysis shows that water in natural reservoirs is a light-attenuating medium both due to attenuation on dispersed particles and due to scattering on nanobubbles. The article analyzes the capabilities of atmospheric and underwater optical communication systems (POS). The results of modeling bistatic PIC in a reservoir containing particles with a diameter of 0.8 ?m and a concentration of 2 х 107 cm-3 are presented. It was shown that the parameters of the bistatic PIC pulses are significantly affected by nanobubbles in water. In natural reservoirs, the use of systems with direct line of sight is preferable. It has been shown that bistatic PICs, in which the scattering region is located on the side of the receiver unit relative to the transmitter — receiver line, have the greatest energy potential and minimal intersymbol interference. In natural reservoirs, it is possible to use such bistatic PICs for communication with a frequency of less than 20 MHz at distances of not more than 20 m. As a scattering region in bistatic PIC, you can use the bottom of the reservoir, the surface of the water or the region of water with a higher turbidity than the rest of the reservoir.
Keywords: laser pulse, water body, attenuation, broadening, telecommunication, turbidity, nanobubbles.
