| 摘 要： | 多普勒天气雷达的基数据主要由气象回波和地物杂波组成,地物杂波过多就会严重损害雷达基数据的精确性,因而多普勒气象雷达想获得质量高的数据产品就必须抑制地物杂波。探讨了如何使用频域滤波技术提高多普勒天气雷达数据质量的问题。

| Abstract: | Doppler weather radar-based data is mainly composed of meteorological echoes and ground clutters, while excessive ground clutters pose serious pollution to the base data. Therefore, ground clutters have to be restrained to acquire high-quality base data. This paper discussed how to use the frequency-domain filtering technique to improve the quality of Doppler weather radar data. |
