The invention relates to radio-electronics and can be used in radio-electronic means for different purposes, in particular in radio-navigation, radio-astronomy, radio-monitoring. In the method for digital correlation radio direction finding radio radiation is received with two fixed, separated in space antennae with following preliminary selection, coherent transformation of frequency and amplification in two radio-channels that are adjusted to given working frequency. Amplified radio-signals are transformed to digital form with determination of complex frequency spectra of those. Then one inverts one of complex spectra. After that one performs shift of those by frequency from band of intermediate frequency to band of working frequency through adding to values of frequencies of spectral components of those values of frequency shift that is equal to difference between given working frequency of adjustment of radio-channels and intermediate frequency. Then one multiplies respective readings of direct and inverted complex frequency spectra obtained through multiplication of arguments of spectral components of the product by coefficients that are inversely proportional to values of respective readings of frequency. One determines extreme value of compensation parameter of one of radio-channels as argument of sum of complex frequency readings of transformed product of spectra. After that by extreme value of compensation parameter for one of radio-channels determined and with account of spatial arrangement of antennae one determines direction to source of radio emission. Technical result is in increase of operation speed of radio direction finding.
