METHOD OF GENERATING MULTILOBED BEAMS OF ANTENNA ARRAYS Russian patent published in 2008 - IPC H01Q3/26 

Abstract RU 2341853 C1

FIELD: physics.

SUBSTANCE: proposed method of generating multilobed beams of antenna arrays is based on weighting signals, received by each emitter, and subsequent addition. The complex weight coefficient in the channel of the n-th element of the array is found, using the partial diagram method, by superposition with certain weight factors Hp of complex currents forming the p-th beam: where N is the number of emitters, using information on the orientation of the main lobes of the directional pattern where d and λ are array spacing and wavelength, and their relative level HP. When determining complex weight coefficients , information on the required values of the phase diagram Ψp in the directions of the formed lobes are used. This is due to that, during superposition of complex currents , complex weight factors are used taking into account the required values of the phase diagram with its signs.

EFFECT: regulation of the phase difference of lobes of the directional pattern when receiving waves from a single source under multi-beam propagation conditions.
