METHOD FOR FORMING COMPENSATIONAL DIRECTIVE DIAGRAM IN A FLAT ANTENNA ARRAY WITH ELECTRONIC BEAM CONTROL Russian patent published in 2023 - IPC H01Q3/26 

FIELD: antenna engineering.

SUBSTANCE: formation of a highly directional scanning radiation pattern of a flat antenna array is carried out using selected complex amplitudes of the antenna elements, taking into account the required excess of the level of the compensation radiation pattern above the level of the side lobes of the highly directional scanning radiation pattern and with a given nonlinear phase shift, the formation of a weakly directional radiation pattern is carried out by summing the signals of the antenna elements, located in orthogonal subarrays of three or more linear antenna arrays of a flat antenna array, with complex amplitudes corresponding to the complex amplitudes of the antenna elements of a flat antenna array in the direction of the source of the useful signal with the same nonlinear phase shift as in the formation of a highly directional radiation pattern.

EFFECT: increasing the sensitivity of the compensation radiation pattern (RP) to interference sources and expanding the spatial area.
