FIELD: measurement equipment.
SUBSTANCE: invention can be used in radio interception, radio monitoring at searching of special electronic information intercept devices to determine location of a radio source (RS). A phase direction finder includes three antennae, three receiving paths, three phase detectors, a frequency metre, an interception unit, a combiner, bearing determining unit, and direction determining unit, which are connected to each other in a certain way.
EFFECT: determination of direction at RS and length at relatively small distances.
