Phase calibration is an important condition for dual-channel TT&C for spacecraft. The influence of angel error demodulation is analyzed in this paper according to the left or right circle polarization electromagnetic wave. The phase of angel error is discussed by different baseband A/D sampling frequency. The calculation model of fast phase calibration is given for dual-channel mono-pulse tracking system. The data of phase calibration is verified by test. By the method proposed, with different IF A/D sampling frequency, the phase errors of the sum and difference channels can be calibrated quickly and conveniently by receiving different circle polarization electromagnetic wave. The success rate of phase calibration is raised as a result.
