Phased-array antenna receiving channel calibration method, system, medium and equipment

The invention relates to a phased-array antenna receiving channel calibration method and system, a medium and equipment. The method comprises the following steps: uniformly dividing a broadband wireless signal received by each array element receiving channel into M sub-bands; after the I array element receiving channels respectively receive and process the wireless signals divided into the M sub-bands, acquiring phases and amplitudes of M frequency points of the I array element receiving channels; selecting one of the I array element receiving channels as a reference channel; obtaining calibration phases of I-1 array element receiving channels under M frequency points according to the phase of the reference channel under the same frequency point, the phases of the I-1 array element receiving channels not serving as the reference channel and the phase relationship among the I array elements; acquiring calibration amplitudes of I-1 array element receiving channels under the M frequency points; and according to
