FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio engineering and can be used to receive signals from different directions to one receiving device. Single-output multi-beam antenna system comprises: an antenna array consisting of spatially spaced antenna elements; a diagram-forming circuit containing blocks of weight coefficients w1, w2,…, wK, which control the shape of the radiation pattern; the adder summing the signals from the outputs of the diagramming circuit, the output of the adder is the output of the antenna system; block for calculating the weight coefficients wk (k = 1,…, K), depending on a priori information about the location of the antenna elements and the parameters of the radiation pattern; a block that forms the expected directions of arrival of signals; block for specifying the parameters of the direction pattern DP. In this case, the outputs of antenna elements of the antenna array are connected to the corresponding inputs of the weighting unit blocks, the outputs of which are connected to the inputs of the adder having one output. Output of the block of formation of the expected directions of the arrival of signals is connected to the input of the block for setting the parameters of the DP. Output of the DP parameter setting unit is connected to the input of the weighting unit, whose outputs are connected to the corresponding inputs of the weighting unit.
EFFECT: technical result consists in the possibility of forming several beams in the expected directions of the signal sources.
