ADAPTIVE ANTENNA ARRAY Russian patent published in 2012 - IPC H01Q3/26 H01Q21/00 

FIELD: physics.

SUBSTANCE: adaptive antenna array comprises N antenna elements, at whose outputs there are N band-pass filters, M×N units for complex signal weighting, M signal adders, a common adder and an adaptive processor. The adaptive processor is in form of a set of M units for generating weight coefficients. M outputs of each of the N band-pass filters are connected for the corresponding frequency component of the useful signal to corresponding inputs of M units for generating weight coefficients directly, and to corresponding inputs of M signal adders through the units for complex signal weighting. Outputs of M units for generating weight coefficients, which are the outputs of the adaptive processor, are connected for the corresponding frequency component of the useful signal to control inputs of units for complex signal weighting. Outputs of M signal adders are connected to inputs of the common adder.

EFFECT: high signal ratio when processing broadband signals with respect to noise signals regardless of their frequency band and power in any signal jamming environment.
