Popis: | To solve the phase deviation problem caused by antenna orientation centre deviation during the phase calibration of Monopulse tracking receiver on ship-borne sitcom station, a phase compensation method is proposed to enhance the phase calibration precision. The working principle of monopulse tracking receiver is discussed, the demodulation process of sum and difference signal, and the cause of phase deviation based on current phase calibration method is analysed. Then, a phase compensation method based on deviation source is proposed, and the phase calibration operation procedure detail is discussed. Results based on the current and proposed phase calibration methods are compared, and the proposed method enhances the phase calibration index effectively, which means a more precise phase result is acquired. |
