Description: The paper considered the possibility of providing the necessary noise immunity, simulated brightness and Criticality of the radio link for controlling an unmanned aerial vehicle, and protecting them against possible suppression by means of electronic intelligence and electronic warfare. It has been established that the apparatus of game theory is used for solving optimization problems. The analysis has been carried out and a methodology has been developed for estimating the average value of an indi-cator of the quality of functioning of a communication system for various strategies of the conflicting parties. The necessity of using dynamic radio control lines of an unmanned aerial vehicle has been substantiated. An algorithm for pseudorandom change in the shapes of wideband complex signals has been developed. Experience in operating unmanned aerial vehicles has shown that the most vulnerable element of the control system. The strategy of the likely adversary may consist either in suppressing the radio link of the control of the unmanned aerial vehicle by means of radio- electronic counterwork, or in the false information entered into the control system of the unmanned aerial vehicle. The solution of the problem is associated with the use of broad-band dynamic modes of functioning of the radio lines of control of an unmanned aerial vehicle based on algorithms of pseudo-random change of the forms of the used broadband complex signals.
