- Abstract
According to the phase calibration requirement for large - caliber antenna multi - feed tracking system in tracking, telemetry and control (TT&C) system, this paper introduces the commonly-used phase calibration methods, and provides a phase calibration calculation method based on fixed wave path difference to overcome the shortcomings of solar phase calibration such as large error, requiring average value, and long calibration time through analyzing the principle of multi-feed tracking system. This method uses the precise value of phase calibrate in different frequency to calibrate the wave path difference between sunm and difference channels in tracking system, then calculates the value of phase in all frequencies. Finally, the range equipment is adopted to perform calibration and validation. The application shows that the method computes fast, the calculation results are stable and available which conform to the change trend of actual data, and it meet the requirements of actual project application.
