| 摘 要： | 以滴谱理论为基础，用模拟雨滴谱分布的方法，讨论了雨滴主普变化以及降水强度变化对双线偏振雷达测雨式的影响，分析了双线偏振雷达测雨式优于普通雷达的原因，进而对回归所得双线偏振雷达各测雨式的测雨精度进行了对比分析，提出子双线偏振雷达各测雨式中的最佳测雨式。

| Abstract: | On the basis of DSD theory ,the method of s imulating DSD with a Gamma distribution function is employed to investigate the effects of the variation in DSD and rain rate on rainfall estimators of dual-p olarization radar to study why the rainfall estimators from dual polarization ra dar are better than that from a conventional radar and to compare the rainfall e stimating error of estimating formulate at each radar working band(X,C and S) .Then we have got the best rainfall estimator of dual polarization radar with a verification by the DSD observed data. |
