FIELD: radio engineering, communication.
SUBSTANCE: method for adaptive and matched suppression of fluctuation noise and concentrated interference in a rational combination of adaptive and matched filtering, which is possible owing to spatial diversity and control of beam patterns of antenna systems and also owing to that, after adaptive and matched interference compensation, the obtained signal is used for further analysis and removal of residual narrow-band interference from the spectrum thereof. The obtained frequency samples of the corrected spectrum of the digital signal from which fluctuation noise and narrow-band interference have been removed is converted to the time domain and used for analysis and selection of pulsed interference, after which current time samples belonging to the interval affected by pulsed interference are blanked.
EFFECT: high noise-immunity when receiving wide-band signals, including with considerable distortion of the shape and spectrum of the useful signal caused by various powerful interference.
