Abstract

One of the most important characteristics of systems and radiocommunication devices operating in conditions of radio-electronic suppression is their secrecy, which is the ability of systems and devices of radio communication to withstand the action of radiotechnical intelligence. One of the ways to increase the noise immunity and stealth the radio communication devices is to use the pseudorandom frequency adjustment technology. The analysis of well-known scientific sources by the author of the article showed that they are oriented to positional signal-code designs and do not use timer signal-code designs. The author of the article is devoted to the development of a method for selecting rational parameters of radio stations parameters with pseudorandom processing of frequency on the basis of timer signal structures in conditions of intentional interference. During the research, the author used the basic provisions of the communication theory, the theory of electron-fight theory, the theory of signals, and general scientific methods of analysis and synthesis. The mentioned technique differs from the existing ones because the method of selecting the parameters of the frequency-time matrix of timer signal structures, depending on the signal-interference situation, implements not only the change in the speed of the adjustment of operating frequencies, but also the change in the initial filling of the polynomial, depending on the type and intensity interference; noise immunity and spectrally effective signal-code designs have been used, improves noise immunity and speed of radio communication during intentional interference. The efficiency of using the algorithm for selecting the parameters of the time-frequency matrix can be estimated by gaining the probability of false reception of signals when the mode is restored from the original. Thus, the total gain from using the developed technique is up to 15-20% compared with the use of frequency modulation and cyclic codes at the same bandwidth under the influence of various types of intentional interference and using the algorithm for the formation of the frequency-time matrix of 20-25%. Taking into account the above, the direction of further research should be considered in the development of a scientific and methodical apparatus for increasing the structural stealth of radio communication devices based on the use of timer signal structures.
