DOPPLER PHASE METER OF PASSIVE NOISE Russian patent published in 2015 - IPC G01R25/00 

FIELD: measurement equipment.

SUBSTANCE: Doppler phase meter of passive noise comprises a unit of phase evaluation, a unit of complex multiplication, a delay unit, a clock generator, the first multiplier, the first functional converter, the second multiplier, the second functional converter, the first memory unit, a complex summator, an additional phase calculator, the second memory unit, an additional unit of phase evaluation, the third and fourth functional converters, an additional unit of complex multiplication and an additional delay unit, which perform coherent processing of source counts with the purpose to measure trigonometric functions (cosine and sine) of current values of the Doppler phase of multi-frequency passive noise.

EFFECT: increased accuracy of measurement of Doppler phase shifts of multi-frequency passive noise.
