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
 is found, using the partial diagram method, by superposition with certain weight factors Hp of complex currents  forming the p-th beam:
 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 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
 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
, 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
, complex weight factors are used  taking into account the required values of the phase diagram with its signs.
 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.
