The combat use of small and medium-class unmanned aerial vehicles (UAVs) in recent local military conflicts, as well as the experience of using UAVs in the operation of the Russian Aerospace Forces in Syria and Ukraine, has shown that they are mainly assigned the tasks of aerial reconnaissance in those areas of the theater of operations (Theater of Operations) where The use of manned aircraft is unjustified or impractical due to the high probability of damage to manned aircraft. The main threats to UAVs in modern theater are the possibility of hitting them with anti-aircraft missile systems (SAMs) of air defense (air defense), as well as the suppression of the command radio control line (CRU) of the UAV by means of electronic suppression (RAP) of the enemy.

The purpose of the work is to develop theoretical solutions aimed at the formalized formation of air defense and RAP zones in the theater based on clustering theory methods for subsequent consideration of these zones in the automated formation of UAV flight routes.

The paper proposes a methodology for the formalized formation of air defense and RAP zones based on the methods of clustering theory. In the future, the air defense and RAP zones are taken into account in the automated route control of the UAV by forming the flight route of the UAV bypassing these zones. The novelty of this solution, which distinguishes it from well–known works in the field of formation of UAV flight routes, is the consideration of two types of destabilizing factors as obstacles to UAV flight - the impact of air defense and REP means. These factors are formalized in the form of an integral metric of nodes in the graph of the geotopological model of the theater flight zone. At the same time, the Lance-Williams mathematical algorithm of hierarchical clustering is used to form «closed for flights» zones in which the probability of UAV damage is high, and areas of control violation due to the impact of RAP means. The connectivity check of the route network is based on the method of determining the strongly connected areas of the graph. The resulting solution makes it possible to increase the stability of UAV control during their combat use in theater equipped with air defense and RAP systems.
