METHOD OF ESTIMATING NAVIGATION SIGNAL PHASE ON BACKGROUND OF INTERFERING REFLECTIONS OF MULTIPATH DISTRIBUTION AND NAVIGATION RECEIVER WITH DEVICE FOR SUPPRESSING INTERFERING REFLECTIONS IN PHASE ESTIMATION

摘要

FIELD: radio engineering, communication.;SUBSTANCE: receiver contains a master oscillator, an RF transducer, a multi-channel digital correlator, a multichannel digital correlation signal processing unit, a receiver timeline generator and a navigation processor. Each channel of the digital correlator comprises a device for suppressing interfering reflections in the phase estimation, and each digital correlation signal processing unit comprises a phase measurement generating unit. The device for suppressing interfering reflections in the phase estimation comprises a weight register, a shift copy register, a plurality of M code-mixers, M accumulators, M multipliers and an M-input combiner, at the output of which the phase estimation of the forward navigation signal is generated.;EFFECT: eliminating the errors in the phase estimation of the direct navigation signal caused by interfering reflected multipath signals.;4 cl, 10 dwg
