To date, small-sized unmanned aerial vehicles (UAVs) have taken an important place in the life of human activity and are used in solving a wide range of tasks: in the civil sphere (for example, for logistics, healthcare, agriculture, emergency rescue operations), for unauthorized surveillance of important objects, for relaying data between remote subscribers of networks communications, for carrying out terrorist attacks and sabotage (for example, access beyond the perimeter of protected objects, obstruction of air traffic at airports), for carrying prohibited goods (weapons, drugs), in military affairs (for example, for reconnaissance, tracking objects, adjusting fire, striking). In parallel with the development of UAVs, methods of combating them are gaining great popularity. So, to counter UAVs, means of fire damage, functional damage by ultrahigh-frequency and laser radiation, radio-electronic suppression, etc. are used. The main means of target designation for these systems are radar stations, optical-electronic, acoustic and electronic reconnaissance, the latter of which have the highest priorities due to the lack of their own radiation, sufficient detection range and all-weather conditions. The article considers a variant of determining the direction to small-sized unmanned vehicles in a phase two-channel radio direction finder with amplitude modulation of the signal. Proposals for the implementation of the bearing assessment method have been developed, shortcomings have been identified and ways to solve them have been worked out. A block diagram of a two-channel phase direction finder with amplitude modulation of the signal has been obtained and its layout has been developed. The structure of checking the quality indicators of the direction finder is considered and the results of the bearing assessment are presented.
