| Abstract: | In order to improve the quality of radiosonde observation and reduce the abnormal balloon tracing, an analysis is made of the phenomenon of balloon loss and side lobe echoes caused by the radar performance, frequency drifting, electromagnetic interference, low elevation angles, and so on. Combined with the actual working experiences, a new method for using the saturated signal principle is presented.Some suggestions, such as the radar precision setting check and battery soak time control, are given. The application indicates that these methods work well. |
