Formulation of the problem in general. Growing role of electronic warfare systems versus unmanned aerial vehicles is one of the trends of the Russian-Ukrainian war. The combat use of such systems requires an assessment of the effectiveness of the processes that occur in the conflict between the forces and means of radio-electronic warfare and the enemy's unmanned aerial vehicles. Such an assessment is necessary for the selection of technical solutions during the development of weapons, as well as the synthesis of local and spatially distributed countermeasures against unmanned aerial vehicles. The formation of such systems is still ongoing in Ukraine. Mathematical models should be a base of assessment tools which must have a reasonable balance between sufficient accuracy, completeness of system capabilities (objects) and simplicity of their modeling. Probability models with such specs are commonly applied in military industries. Research methods. Following methods and theories were applied during case study: principles of the systematic approach, methods of probability theory, systems modeling, elements of the theory of signal detection and methods of the theory of qualimetry. Analysis of recent researches and publications. It was determined that the modeling of the functioning of radio-electronic warfare systems mainly covers the description of jamming signals, the structure of radio-electronic warfare devices, their individual structural or functional components, individual processes, etc. The majority of existing models cover the effect of radio interference in details only for certain subset of on-board equipment installed in unmanned aerial vehicles. Some models are too abstract. At present there is no such single mathematical model which can cover all functioning aspects of radio-electronic warfare system in combat with unmanned aerial vehicles. Presenting the main material. Key results of case study: processes of "radio-electronic warfare system - unmanned aerial vehicles of the enemy" conflict were ...
