FIELD: radiolocation. SUBSTANCE: facility for angle tracking is designed to be used in mix of radar systems tracking by direction and possessing Doppler selection. Facility for angle tracking includes antenna with summary-difference converter connected to it, two mixers, two intermediate frequency amplifiers, two phase detectors, two envelope detectors, two Doppler filters, heterodyne, former of gating pulses, coherent heterodyne, phase detector of error signal, amplifier, motor structurally coupled via reduction gear to antenna, two band- pass filters tuned away by frequency from mentioned Doppler filters, additional phase detector of error signal, decision-making device, comparator, amplitude detector and receiving antenna of orthogonal polarization mechanically united with main antenna, receiver and second amplitude detector connected in series. EFFECT: development of facility for angle tracking displaying high degree of protection against effect of cross polarization noise. 1 dwg
