a new outfield calibration method is presented based on phase interferometric
and phase difference formula is derived with the combination of overdetermined equations solution.Special state shift is realized with phase shifter
and phase difference is obtained by multiple channel power synthesis.The mechanism analysis and the outfield experiments show that this method is efficient and correct.
