FIELD: range meters. SUBSTANCE: phase meter has frequency former 1, carrier transmitters 2, 16, carrier receivers 3,14, mixers 4,5, phase meters 6,7, integrators 8,9, lower frequency filters 10, 12, adder 11, constant voltage divider 13, modulating frequency amplifier 15. Influence of Doppler effect and signal delays at range finder units may be eliminated at combined processing of phase shift measured at two subcarrier frequencies. EFFECT: improved precision of measurement. 1 dwg
