FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and intended for Doppler phases shifts (object radial velocity) measuring of not equidistant coherent-pulse radio signals on background of noise; can be used in radio-locating and navigation systems for of aircraft Doppler velocities unambiguous measurement. Coherent pulsed radio signals phase meter contains delay unit, complex conjugation unit, complex multiplication unit, averaging unit, phase computation unit, a switch, unit for calculating module, threshold unit, memory unit, clock generator, first and second two-channel switches, additional averaging unit, a control unit, additional delay unit, additional complex conjugation unit, additional complex multiplication unit, additional multiplier and additional memory unit, implementing initial readings inter-period processing for moving object Doppler (radial) speed unambiguous measurement.
EFFECT: technical result consists in possibility to receive required range of unambiguously measured Doppler speeds while keeping unambiguous distance measurement.
