PHASE METER OF COHERENT-PULSE SIGNALS Russian patent published in 2014 - IPC G01R25/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment and is designed to measure Doppler phase shifts (radial speed of an object) of coherent-pulse periodic radio signals on the background of noise; may be used in radar and navigation systems for unambiguous measurement of Doppler speed of aircrafts. The phase meter of coherent-pulse signals comprises a delay unit, a complex coupling unit, a complex multiplication unit, an averaging unit, a phase calculation unit, a unit of measurement limits correction, a key, a unit of module calculation, a threshold unit, a memory unit, a synchronous generator, an additional delay unit, an additional complex coupling unit, an additional complex multiplication unit, an additional multiplier and an additional memory unit, which perform the processing of initial counts between periods with the purpose of unambiguous measurement of Doppler (radial) speed of a moving object.

EFFECT: application of a phase meter of coherent-pulse signals makes it possible to produce required range of unambiguously measured Doppler speeds with preservation of unambiguous measurement of distance, which is the achieved technical result.
