Description: The main disadvantage of remote control systems is the violation of the integrity of the control channel from the effects of firefighting and mechanical factors. This is because the control mainly uses a wired communication channel that has a large length and a high probability of damage. One of the ways to improve the reliability of a communication line is to switch to radio channel control. But in this case, it is necessary to solve the problem of impedance of the radio link of data transmission from the active interference of the stations of electronic warfare and interference managers of one-time action. Modern radio communications lines are usually built on the basis of the use of noisy signals. Currently, 3G and 4G technologies are the most used, based on a combination of multi-frequency and time-coded signals. In this case, one of the main requirements for the signal, one can consider the simplicity of managing its parameters with an acceptable complication of the mechanisms of formation and processing. From this point of view, certain advantages over other complex signals is the multifrequency signal generated by the method of angular modulation of the high-frequency radio pulse of periodic voltage. Autocorrelation and inter-correlation properties of multifrequency signals allow us to draw conclusions about the use of methods and devices of autocorrelation and inter-correlation processing of coherent multi-frequency signals in the spectral region for the control of interference in the radio channel of the remote control of the weapon. The article analyzes the possibility of using modern technology of data transmission, which is based on a combination of multi-frequency and time-coded signals for the purpose of their use in remote-control systems of armaments.
