| Abstract: | The paper aims to improve the operational quality of radar. The antenna and feeder line attenuation measurement was introduced to the original calibration method for CINRAD/SC weather radar, and rational calibration process of radar of this model was set in order to improve data quality. Signal sources and power meter were used to carry out attenuation measurement respectively on the emitting and receiving parts of the radar, and measurement positions and measurement method were obtained. In combination with radar equations and radar operating principles, the authors discussed and proposed a rational calibration method for radar of this model. Taking into consideration the performance indexes of Chengdu radar station, the authors also analyzed the influencing degrees brought by main radar parameter performances to the radar echo intensity, and finally compared the echo diagrams obtained before and after the application of the calibration method. The results showed that the method proposed in this paper could effectively complete radar calibration and improve the calibration quality of radar. |
