Abstract
A phase calibration method includes: segmenting a received measurement sequence according to a preset rule; respectively determining a phase calibration factor of each of segmented measurement sequences, wherein the each of the segmented measurement sequences respectively corresponds to a segmented phase; and when performing a phase calibration on a sequence to be verified, according to a matching relation between a phase of the sequence to be verified and the each of the segmented phases, using the phase calibration factor corresponding to a matched segmented phase to perform the phase calibration on the sequence to be verified. The embodiments of the phase calibration method and the device are equivalent to dividing a non-linear measurement sequence into several approximately linear measurement sequences, and then calibrating each of the several approximately linear measurement sequences using a corresponding phase calibration factor respectively.
