Abstract: There are relatively obvious random errors in solar calibration data of CINRAD/SC weather radar system, so it suggests that the data should not be used directly as the basis in the course of correcting the direction of the antenna electrical boresight. According to the data creation process of solar calibration method in CINRAD/SC weather radar system, it indicates that the main reason causing the errors is the “time warping”. The methods and steps eliminating this kind of errors are put forward based on the rule of producing errors, and the corresponding formulae are also given. The corrected data of solar calibration method are used as the basis adjusting the direction of the antenna electrical boresight, which is helpful to improve the directional accuracy of the new generation weather radar system.
