Abstract: The present invention relates to the communications field, and provides a phased array calibration method and a phased array calibration circuit. The phased array calibration circuit includes a signal obtaining module, a selector, a phase difference module, and a main signal module. The selector is configured to switch on the signal obtaining module and the main signal module; the signal obtaining module is configured to obtain a first signal according to an initial signal after the selector switches on the signal obtaining module and the main signal module; the selector is further configured to switch on the phase difference module, the signal obtaining module, and the main signal module; and the signal obtaining module is further configured to obtain a second signal according to the initial signal after the selector switches on the phase difference module, the signal obtaining module, and the main signal obtaining module.
