| 摘 要： | 数字化天气雷达定量探测的精度误差与雷达标定的误差有直接关系。特别是对于双线偏振其差反射率因子ＺＤＲ的典型值又为－３－＋５ｄＢ，而不同类型降水物的ＺＤＲ值可能仅相差十分之几分贝，因此，雷达标定的精度是至关重要的。

| Abstract: | It is very important to the calibration method of digitized weather radar and dual-linear polarization radar,because the precision of radar data is related with calibration error of radar,especially for dual-linear polarization radar,the normal value of Z DR is only -3 0 +5 0dB and the difference of Z DR is less than 1dB for different kind of precipitation.In this paper,a calibration method of above-mentioned radar is introduced .It is useful for weather radar practical research. |
