METHOD OF PROCESSING SIGNALS IN MODULAR ADAPTIVE ANTENNA ARRAY DURING RECEPTION OF CORRELATED SIGNALS AND INTERFERENCE

摘要

FIELD: communication.;SUBSTANCE: invention relates to radio engineering and communication. Feature of disclosed method of processing signals in modular adaptive antenna array during reception of correlated signals and interference is that signals corresponding to branched part of power converted into M signals, in which there is no component of useful signal, is based on information on directivity modules such change of M converted signals into M_a interfering signals so, that complex amplitudes of components of noise in them approach complex amplitudes of interference in output signals of corresponding modules, while using obtained M_a signals of covariance matrix of noise and size of M_a×M_a, finding optimum for modular adaptive antenna array based on criterion of maximum signal-to-(interference + noise) vector complex weight coefficients, signals, corresponding to part of power summed in M_a modules with specified complex weight coefficients.;EFFECT: high efficiency of suppressing interference, correlated with useful signal.;1 cl, 6 dwg
