The invention can be used in radio-electronic means for different purposes, in particular in radio-navigation, radio-location, radio-astronomy, radio-monitoring. Radio-frequency emission is received with two fixed separated in space antennas, with following preliminary selection, transformation of frequency and amplification in two radio-channels. Then the formed radio-signals are transformed to digital form, with determination of complex frequency spectra of those. After that inversion of one of complex frequency spectra is performed. Then readings with same frequencies of direct and inverse complex frequency spectra are multiplied, with obtaining the product of complex frequency spectra, this is transformed through adding linear-frequency phase shift to phase-frequency component. Then the array of real frequency components of transformed product of complex frequency spectra is separated. After that the argument of complex amplitude of the component of separated array of real frequency components is determined, with frequency corresponding to the slope of the linear-frequency phase shift. After that the extreme value of the linear-frequency phase shift is determined as argument of complex amplitude of the spectrum component of separated array of real frequency components. The direction to the source of radio radiation is determined by the extreme value of the linear-frequency phase shift determined, and with account of spatial placement of antennae. The technical result is in increase of operating speed of direction finding.
