The method of maximum plausibility in the problems of protection of the radio signal of unmanned aerial vehicles control

The paper considers the problem of protection of control of the radio signal of control of unmanned aerial vehicles as a task of control of signal parameters. The problem of control of a parameter of a radio signal and a problem of protection against interception by control of the unmanned aerial vehicle is formulated. The methods of estimating the parameters of the radio communication signal are analyzed and the method of estimating the parameters based on the method of maximum likelihood is proposed. This technique is demonstrated by estimating the phase of harmonic oscillation, which describes the radio signal and there are noise interference. Simulation modeling of the developed method is carried out, which confirmed the adequacy of the proposed model.
