The experience of the Russian-Ukrainian war shows that an effective way to counteract unmanned aerial vehicles is by jamming the receivers of their radio control channels. For this purpose, short-range electronic warfare systems are widely used in the tactical level. During the formulation of requirements for such systems, as well as the planning of their intended use, there is a need to calculate their effective zones of action. A mathematical model for the process of radio jamming unmanned aerial vehicles control channels receivers, which takes into account the technical parameters of the radio channel and the jamming transmitter, the heights of their antennas, and their radiation patterns are developed in the article. It is shown that the radio jamming zone of an interference transmitter with an omnidirectional antenna is limited by a sphere in space, and by circles on the ground surface, the centers of which are shifted relative to the location of the jamming system. The use of directional antennas makes it possible to increase the range of the jamming transmitter, but the jamming zone will be sectoral in space, and its shape will depend on the antenna's radiation pattern. Four methods for calculating the radio jamming zones of jamming transmitters against unmanned aerial vehicles control channel receivers, corresponding to the most common practical cases of their application, are proposed in the article. Software for calculating and graphically displaying the jamming zones has been developed in the MATLAB programming environment. Examples of using the proposed methods for calculating the radio jamming zones of individual protection active jamming systems with ''dome-type'' antennas and group protection systems with directional antennas are given.
