The novelty of the research lies in the fact that for the first time a model of radio lines was developed using spatio-temporal processing of broadband signals to provide communication sessions for the needs of officials of situational centers of an integrated security system, the dependence of the number of receiving and transmitting paths of the communication system on the signal-to-noise ratio was obtained. Result: the presented solution to the model of radio lines using spatio-temporal processing of broadband signals is fully suitable for the needs of officials of situational centers of an integrated security system for transmitting data and providing a transport layer of protocols of modern communication services in those places where laying fiber-optic communication lines is difficult or impossible. The results obtained by comparing the noise immunity of MIMO and SIMO systems for non-uniform and time-variable channels have shown the significant superiority of the developed radio link model using spatial-temporal processing of wideband signals. Using the mathematical modeling program MatLab, such a model was built and a comparative study of noise immunity with other well-known radio lines was carried out.
