METHOD FOR RADIO SIGNAL SOURCE DIRECTION FINDING Russian patent published in 2020 - IPC G01S3/10 G01S5/06 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering and can be used in mobile systems and a backup supplement to stationary radio reconnaissance and radio monitoring systems, radio navigation and radio monitoring to determine direction of radiation source or angles of arrival of radio waves, mainly in decametre range of radio waves lengths. Said result is achieved by using a phase method when placing antennas on unmanned aerial vehicles located at a distance from the ground, introduced by receiving-transmission units of direction-finding radio signals and control signals, retranslating direction-finding signals between unmanned aerial vehicles, on-board navigation systems and a ground-based control and indication module for processing an array of direction finding, indication and recording results.

EFFECT: technical result of invention consists in expansion of application fields, reduction and compensation of errors in determination of bearing, reduction to a pair of used antennas used for direction finding, with efficiency of a circular antenna array of a plurality of antennae and potential implementation of a wide-base direction-finding system, without considering the effect of the area and the environment by ground-based re-radiators.
