FIELD: electronic warfare.

SUBSTANCE: invention relates to electronic warfare and can be used to increase efficiency of jamming while providing covert guidance of a pair of interceptors to an aerial target. Disclosed is a method of controlling spatial position and operating modes of an on-board active jamming station to ensure concealed homing of a pair of interceptors to an aerial target. Two interceptors are equipped with active jamming stations, and their on-board radar stations are combined into a system with information exchange channels, an attacking interceptor with an on-board radar station operating on radiation and a cover interceptor with an active jamming station operating on radiation is determined. Design features of the active jamming station make it possible to control the power of the transmitter and the coefficient of directional action of the antenna. At the beginning of guidance, the radiated power of the active jamming station and the directivity factor are set to minimum values. Covering interceptor with an active jamming station operating on radiation performs a targeted approach to an attacking fighter in the process of its guidance, providing, on one side, maximum efficiency of cover, since when approaching the covering object, the interference formed to suppress the enemy on-board radar station is set according to the maximum of the main lobe of its antenna pattern, on the other hand, providing operation of an on-board radar station of an attacking interceptor with a given efficiency, which can be reduced due to an increase in the level of unintentional interference as a result of approach. When the distance between the interceptors of the pair reaches the critical value determined by flight safety, the cover interceptor switches from controlling its spatial position relative to the attacking interceptor to controlling the radiation power of the active jamming station, while maintaining a fixed distance between the interceptors of the pair. Increase of active jamming power as well as spatial position control will lead to higher efficiency of jamming. When the value of the radiated power of the active jamming station reaches the maximum value, the power value of the active jamming station is fixed at the maximum value, and the active jamming station changes from controlling the radiated power to controlling the coefficient of directional action of its antenna.

EFFECT: increase in the duration of concealed guidance of a pair of interceptors to an aerial target due to successive control of the spatial position of the interceptor – the carrier of the active jamming station, its power and the coefficient of directional action of the antenna of the active jamming station.
