It is proposed to use MIMO technology in NLOS systems. The system operates in the optical short-wave ultraviolet range of radio waves. MIMO technology uses orthogonal polarization multiplexing of coherent laser radiation from two sources. Spatial channels use the reflection from spatially separated regions of molecular scattering. Another proposal to increase the reliability of the NLOS system is to increase the radiation power on the transmitting side by using a group of laser sources instead of one. The third proposal in the work is the integration of laser sources with an array of optical fibers. The array of optical fibers forms a radiating aperture. This solution allows us to solve the problem of controlling the shape of the radiation pattern of the radiating aperture. Suggestions are made to reduce the level of lateral radiation and spurious polarization due to the diagonal elements of the matrix of the radio channel.References
