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.

Устройство пространственно-временной компенсации помех относится к радиотехнике, в частности к технике радиоприема, и может найти применение в гидроакустике. Изобретение решает задачу повышения помехоустойчивости приема дискретной информации в многолучевом канале с переменными параметрами. Устройство содержит N-элементную антенную решетку, N блоков задержки, N линий задержки, N детекторов-режекторов, (N -1) блоков попарного вычитания, устройство формирования лучей (УФЛ) по алгоритму Фроста, вспомогательное УФЛ и демодулятор многолучевых сигналов. Схемное решение устройства позволяет исключить попадание полезного сигнала в устройство формирования лучей ДН. В результате полезный сигнал не испытывает подавления во вспомогательном УФЛ и повышается отношение сигнал/помеха на выходе устройства.The device spatio-temporal noise compensation relates to radio engineering, in particular to the technique of radio reception, and may find application in hydroacoustics. The invention solves the problem of improving the noise immunity of receiving discrete information in a multipath channel with variable parameters. The device contains an N-element antenna array, N delay units, N delay lines, N notch detectors, (N -1) pair subtraction units, a Frost beamforming device (UVL), auxiliary UVL and a multipath demodulator. The circuit design of the device eliminates the ingress of a useful signal into the beam forming device of the beam. As a result, the useful signal does not experience suppression in the auxiliary UVL and the signal-to-noise ratio at the output of the device increases.
