PHASE METHOD OF DIRECTION FINDING AND PHASE DIRECTION FINDER FOR ITS REALIZATION

摘要

FIELD: radio navigation, determination of positions and movement of sources of radiation of complex signals. SUBSTANCE: proposed method can be realized by means of phase direction finder that includes receiving antennas, high-frequency amplifiers, first heterodyne, mixers, amplifiers of first intermediate frequency, second heterodyne, amplifier of second intermediate frequency, multipliers, narrow-band filters, frequency meters, computer, register, adders, phase inverter, +90 degrees phasers, amplitude detector and key. EFFECT: enhanced noise immunity and precision of phase direction finding by suppression of spurious signals received through additional channels. 2 cl, 4 dwg
