摘　　要：回顾了近30年来中国双线偏振天气雷达的研究进展,着重从雷达数据质量控制和雷达偏振参量的测量精度两大方面进行详细叙述。阐述了目前主要通过提高双偏振天气雷达的系统性能,降低系统误差,抑制雷达地物杂波,来提高雷达数据质量和测量精度,而双通道一致性和极化隔离度是双偏振天气雷达系统最主要的性能指标;描述了双偏振天气雷达系统及其产品应用新进展。This paper reviews the research progresses of dual polarization weather radar in China with emphasis on radar data quality control and the measurement accuracy of radar polarization parameters in recent 30 years. It is elaborated that the radar data quality and the accuracy of radar polarization parameter measurements are mainly improved by means of system improvement,system error reduction,and radar ground clutter suppression. The double channel consistency and polarization isolation is the most important performance indicators of dual polarization weather radar. The new progresses of dual polarization weather radar system and its applications are also discussed.
