A fast offset phase calibration method

The phase correction algorithm of dual channel mono-pulse radar is studied in this paper. The angle error voltage of the tracking receiver is represented by a complex number. The expression of the relation between the corrected phase and the corrected slope and the error voltage is derived, and a fast phase detection method is proposed. phase detection rate of this method is significantly faster than the automatic phase calibration of the equipment itself for the case of without the boresight tower. Moreover, the method presented here has higher accuracy.
