FIELD: radio electronics.
SUBSTANCE: result is achieved by means of application of mirror channels of reception and simultaneous direction finding of several sources of phase manipulation-signals radiation. Phase direction-finder contains three receiving antennas, three amplifiers of high frequency, two heterodynes, seven multipliers, seven amplifiers of intermediate frequency, frequency multiplier by two, eight narrow-band filters, seven phase detectors, two correlator units, eight threshold units, thirteen switches, four correlators, registration unit, four amplitude detectors, which are connected in a certain manner between themselves for achievement of specified technical result.
EFFECT: expansion of working frequencies range without expansion of heterodynes frequency tuning range.
