Abstract

FIELD: radio engineering, in particular, radio communications and hydroacoustics. SUBSTANCE: device has K-element antenna array, K delay gates, unit which generates beams using Frost algorithm, additional unit which generates beams, demodulator and K-1 units of pair-wise subtraction. Device provides possibility to exclude entering of signal components to control input of unit which generates beams using Frost algorithm. This results in fact that received signal is not processed by Frost algorithm and in additional unit which generates beams. This leads to increased signal-to-noise ratio at device output. EFFECT: increased stability to noise by means of adaptive noise compensator with rejection of received signal in adaptive control circuit.

The device relates to radio engineering, in particular, to radio communication technology and can be used in sonar. The invention solves the problem of increasing the noise immunity of a radio communication using an adaptive interference compensator with notching a useful signal in an adaptive control circuit. The device contains a K - elemental antenna array, K delay units, a beam forming device (UVL) according to the Frost algorithm, auxiliary UVL, a demodulator, and (K - 1) pairwise subtraction blocks. The circuit solution allows to exclude the ingress of the components of the useful signal to the control input of the beam forming device according to the Frost algorithm. As a result, the useful signal is not processed in the UVL according to the Frost algorithm and in the auxiliary UVL and the signal-to-noise ratio at the output of the device increases, i.e. the noise immunity of receiving discrete information is increased.
