| 摘 要： | 利用点匹配法计算了不同雨滴谱分布的降雨雷达体反射率，结果表明M—P分布与我国实测雨滴谱的结果比较接近，同时进一步分析了降雨雷达体反射率的频率、极化特性等。根据计算结果，研究得到了体反射率的新解析公式，其与点匹配法计算的结果有较好的一致性。

| Abstract: | Basing on several rain drop spectrum distributions, the rain volume reflectivity is obtained by point matching technology. The results show that the Marshall Palmer distribution is close to the measured distributions in China, and the dependence of rain volume reflectivity on frequency and polarization is also analyzed. A new analytical formula is obtained according to the results of calculation, which is in good agreement with the calculated results. |
