Abstract
Base on the classic REV method, a new combined REV method is proposed for the calibration of large-scale phase array. Different from the classical method, the new method synchronously alters the phases of a group of elements by their phaseshifters. When this method is used in nearfield calibration, the signal-to-noise ratio is improved and the dynamic range of the signal is limited, and higher precision could be achieved.
