Description: One of the main methods of targeting operational-tactical missiles is the method of command control, which is based on the use of the command radio link. The operation of the command radio link is largely determined by the possibility of the radio channel functioning, the main task of which is to ensure the transmission of information to the required range of the cruise missile with the required quality, namely, the necessary signal-to-noise ratio at the receiver input. The article deals with the functioning of the radio link of the command radio link of cruise missiles of operational-tactical range. It is shown that the main limiting factors in the organization of a medium-long and long-range radio channel in the VHF band are the need to provide the range of radio visibility and the budget of the radio channel. The main factors affecting the budget for the radio channel are: the directional properties of the antennas, the transmitter power and receiver sensitivity, as well as the variable characteristic associated with the estimation of the signal attenuation during propagation along the radio path. A comparative analysis of two models of signal attenuation estimation is carried out: a stationary (statistical) model and a statistical model for predicting the main transmission losses. The considered approach to the calculation of the radio channel budget of the command radio link can be used in the design of command radio lines for cruise missiles, both airborne and ground-based.
