PHASED ARRAY CALIBRATION METHOD AND PHASED ARRAY CALIBRATION CIRCUIT

摘要

Provided are a phased array calibration method and a phased array calibration circuit, which relate to the field of communications. The phased array calibration circuit comprises: a signal acquisition module, a selector, a phase difference module and a master signal module. The selector is used for turning on the signal acquisition module and the master signal module; the signal acquisition module is used for obtaining a first signal according to an initial signal after the selector turns on the signal acquisition module and the master signal module; the selector is further used for turning on the phase difference module, the signal acquisition module and the master signal module; and the signal acquisition module is further used for obtaining a second signal according to the initial signal after the selector turns on the phase difference module, the signal acquisition module and the master signal module, so as to obtain a phase error and an amplitude error of a phased array channel according to phase information and amplitude information about the first signal and phase information and amplitude information about the second signal.
