This paper introduced the principle of angle errors in tracking system.The demodulation was only related to signal envelop, and supported the phase calibration of radio star.And CAL/MAG 2:1 this paper which is combined with the commonly-used phase calibration methods, carried out the phase calibration of radio star and the satellite on the specific device, summarized the procedure of radio star for phase calibration and compared the accuracy of it.
On the basis of analyzing the theory of phase calibration, the authors concluded the relationship between the parameter of phase calibration and the working frequency.Through utilizing the results of satellite phase Billy Royal Show Halters calibration to verification and the results of phase calibration of radio star on full-band, and achieving the parameter of phase calibration without the calibration tower, it has a good engineering practice value.
