根据偏振雷达原理，用C波段双线偏振天气雷达观测得到4例强对流雹暴演变过程的水平反射率ZH(dBZ)和差分反射率ZDR(dB)垂直剖面RHI定量回波资料，分析了这些雹云不同演变阶段的回波参量和偏振特性的关系，说明ZH、ZDR双参量对判别降雹有着明显优势，用雨滴谱的ZH-ZDR分布边界关系对这些雹云回波进行判别降雹分析，给出我国用偏振雷达观测和识别冰雹的研究结果。

Detailed echo information of horizontal reflectivity ZH and differential reflectivity ZiDR were obtained by C-band dual linear polarization weather radar observations of four hailstorms in evolution process in August 1990. And based on polarization radar principles, we have analysed these echo parameters and polarization characteristic in their different evolution stages, and found ZoR echo column is a distinct echo signature for discriminating fallhails. We have also used ZH and ZoR dual parameters technique to identify hails from mixed rains and hails, and analysic the results.
