Abstract:
In the past few decades，the Fengyun meteorological satellites have progressed from the experimental phase to the operational phase. The reliability and pointing accuracy requirements for satellite signal receiving antennas are getting higher and higher. The 12meter and 4.2meter diameter antenna are used to receive the signals of the Fengyun satellites at present. The characteristics of the antennas are high speed and narrow width of the wave width, and so accurate calibration is necessary when an antenna is built. On the basis of the traditional calibration method, this paper puts forward the error calibration technique using the sun, which can further reduce the complexity of the calibration link and improve the calibration accuracy.
