FIELD: radio navigation.
SUBSTANCE: invention relates to radio navigation and can be used to determine angular coordinates of sources of phase-shift keyed radio signals with a known structure in the presence of radio interference. Correlation-phase direction-finder comprises two antennae, two high-frequency units, two demodulators, two spectral analyzers, a spectra comparison unit, two memory devices, a delay meter between the peaks of the mutually correlated functions and two matched filters which, at their outputs, form the mutually correlation functions between the input phase-shift keyed signal and the code contained therein, provided that the listed components are interconnected in a certain manner.
EFFECT: determining the position of phase-shift keyed signal sources with a predetermined structure.
