Abstract
FIELD: radio engineering. SUBSTANCE: invention can also find use in underwater acoustics. Device for spatial-time compensation of noises includes N-element array, N delay units, N delay lines, N detector-rejectors, (N-1) units of pairwise subtraction, former of beams by Frost algorithm, auxiliary former of beams and demodulator of multibeam signals. Design of device makes it possible to exclude hitting of former of beams of directivity pattern by legitimate signal. As result legitimate signal does not suffer suppression in auxiliary former of beam and signal-to-noise ratio across output of device increases. EFFECT: increased noise immunity while receiving discrete information in multibeam channel with variable parameters.
