METHOD FOR FORMING WEIGHT COEFFICIENTS IN THE PROCESSING CHANNELS OF A BROADBAND ADAPTIVE ANTENNA ARRAY Russian patent published in 2023 - IPC H01Q3/26 

FIELD: antenna technology.

SUBSTANCE: proposed method for the formation of weight coefficients in the processing channels of a broadband adaptive antenna array consists in the fact that the additive mixture of a broadband signal and interference using bandpass filters is divided into narrowband frequency intervals, for each of which at certain frequencies ω_k the optimal vector of weight coefficients W (ω_k) is found, for other frequencies of processing the spectrum of the useful broadband signal, quasi-optimal weighting coefficients are found based on various interpolation functions. Moreover, the optimal vector of weight coefficients is found with a smaller frequency interval at those frequencies of the useful broadband signal where the spectral density of the useful broadband signal is low and with a large interval at those frequencies where the spectral density of the useful broadband signal is high.

EFFECT: rational distribution of frequencies in which the vector of weight coefficients is optimally determined, taking into account the spectral density of the useful broadband signal.
