METHOD FOR ADAPTIVE SPATIO-TEMPORAL SIGNAL FILTERING IN THE ANTENNA ARRAY Russian patent published in 2023 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is used in radio communication systems operating in a complex interference environment. In a method based on the methods for digital generation of the radiation pattern and filtering of signals in the time domain, according to which an interference component is allocated from the digitized quadrature signals of the receiving channels of the antenna array, which is subtracted from the signal of the antenna array, phased in the expected direction of arrival of the useful signal, the received difference signal is processed by a multi-channel adaptive filter, through other channels of which digitized quadrature signals of the receiving channels of the antenna array are received, at the same time, the stochastic gradient method is used as an adaptation algorithm.

EFFECT: increase in the noise immunity of a receiver based on an antenna array in conditions of partial uncertainty over the spatial parameters of signal and interference sources.
