RADIO-FREQUENCY RADIATION SOURCE DIRECTION-FINDING METHOD Russian patent published in 2016 - IPC G01S5/04 G01S3/10 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio systems for determining angular coordinates of a signal source. Said result is achieved by that before receiving the taken a fix signal using a test signal source for various frequencies of calibration and all direction-finding channels, each of which includes an element of the antenna array, calibration coefficients are estimated, each of which determines non-identity of amplitude-phase characteristics of the corresponding direction-finding channel, during direction finding before calculating Fourier spatial spectra of the taken a fix signal the calibration frequency is assessed, performed is dividing the signals received by the direction-finding channels into appropriate, by channel and frequency, calibration coefficients.

EFFECT: provided result is increased accuracy of direction finding of a radio-frequency source of a broadband signal while maintaining uniqueness of measurement of signals at outputs of direction-finding channels.
