METHOD OF FORMING BEAM PATTERN OF ACTIVE PHASED ANTENNA ARRAY Russian patent published in 2019 - IPC H01Q3/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering and can be used to create intentional radio interference of high power to devices for receiving navigation consumer equipment (NCE) operating on signals of global navigation satellite systems (GNSS) and placed on mobile devices. Quality of coordinate-time navigation support (CTNS) is one of the dominant factors determining efficiency of modern weapons and military equipment in armed conflicts. Therefore, task of suppression of enemy GNSS NCE receiving devices is the important task of protection against enemy attack means using CTNS. Purpose of the present invention is a method of increasing the width of the ATFAA pattern in the vertical plane and enabling the on-line control of the beam pattern. Technical result is provided by the fact that the required polarization diagram of the active phased antenna array containing the synchronous interference signal shaper, the vertical antenna array containing the K antennas, K-1 phase changers, phase changer control unit, provides formation of a beam pattern using phase changers, creating phase shifts of emitted signals from the second antenna according to rule Δϕ, 2Δϕ, …, (K-1)Δϕ, which generates the required beam pattern by selecting only one parameter Δϕ.

EFFECT: enlarging the suppression zone of GNSS NCE receiving devices, both ground and air, and operational control of the beam pattern.
