DIRECTIONAL RADIO Russian patent published in 2005 - IPC

FIELD: radio engineering.

SUBSTANCE: the proposed invention may be used in the means of radiolocation, radio navigation and radio reconnaissance for determining the direction on the source of radio wave emission or reflection. The invention essence consists in shaping the signals of "interception" and "union", hardly connected by a general region, determining the time of read-out of a measured parameter. The result is achieved owing to introduction of: 1) amplifier, contacted through an input with the output of the limiter of negative signals; 2) the summing circuit, contacted through the first and second input with the outputs of a video amplifier of total and difference channels; 3) comparison device, contacted through the first and second input with amplifier output.

EFFECT: increased accuracy of direction finding.
