Weather Doppler radar has the advantage of wide measurement range, high spatiotemporal resolution and so on, which can acquire quantitative rainfall data covering large area and have well spatiotemporal representative. This paper summarizes the application progress and up-to-date research of Doppler radar through studying quality control of radar data, gauge-radar adjustment, coupling weather radar application based on achievements of Weather Doppler Radar application both here and abroad. The results show that the radar will continue to achieve its powerful advantages with the deepening of applied research, although the accuracy of radar rainfall is still low and the application depth is not enough.% 多普勒天气雷达具有测量范围广、时空分辨率高等优点，可获得大面积定量降水数据，具有较好的时空代表性。基于国内外多普勒天气雷达数据资料的应用研究成果，从雷达数据质量控制、联合雨量计校正、耦合天气雷达的应用等方面，对应用研究进展与最新动态进行综述。结果表明，虽然当前雷达探测降雨的精度仍较低，应用深度也不够，但是随着应用研究的深入，雷达将不断实现其具有的强大优势
