FIELD: measuring equipment; radio engineering and communication.
SUBSTANCE: invention relates to measuring technology and may be used in radio communication systems, radiolocation, radio monitoring for measuring the frequency shift of radio signals received from one source and differing in frequency and time delay simultaneously. Radio signals are converted into power density spectra, the mutual correlation function of the power density spectra is determined, the maximum position of which is judged on the frequency shift between the radio signals.
EFFECT: method makes it possible to improve the accuracy of measuring the frequency difference between radio signals.
