METHOD FOR COMPENSATING INTERFERENCE SIGNALS IN COMBINED ADAPTED ANTENNA ARRAY Russian patent published in 2021 - IPC H01Q3/26 H01Q21/00 

FIELD: radio-technical navigation.

SUBSTANCE: invention relates to antenna technology and can be used in radio-technical navigation systems when receiving navigation signals by the consumer navigation equipment of the global navigation satellite system (GNSS CNE) under conditions of deliberate interference. The aim of the invention is to increase the signal-to-noise ratio at the output of an adaptive antenna array. This goal is achieved by the formation of a clean output signal containing mainly navigation signals, as a result of subtraction from the received by the central antenna element having a radiation pattern close to uniform in the upper hemisphere, navigation signals and interference signals of the resulting compensating signal obtained by summing the compensating interference signals of each channels formed in the blocks of complex weighting of the signals of the beamforming circuit by multiplying the signals of the peripheral antenna elements having a radiation pattern with a minimum in the vertical plane and a maximum in the horizontal plane and receiving mainly interference signals by the weight coefficients received from the adaptive device, where they are calculated based on the input signals of the peripheral antenna elements and the output signal of the antenna array.

EFFECT: ability to compensate for interference signals that significantly exceed the level of useful navigation signals, and to select useful navigation signals by increasing the signal-to-interference ratio at the output of the adaptive antenna array.
