FIELD: radar ranging and radio navigation.
SUBSTANCE: invention relates to the field of radar, radio navigation and can be used to determine the angular coordinates of the radiation sources of signals. Technical result is achieved due to measurement of signal level after correlation processing, when the specified threshold is exceeded, moment of short-term radiation source switching on is fixed, due to measurement of quadrature values of signals of constant radiation source to moment of short-term radiation source switching on and after its deactivation, due to use of these values when calculating time shift of signals of short-term radiation source.
EFFECT: technical result of the invention consists in solving the problem of simultaneous direction finding of a constant radiation source and a short-term radiation source.
