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雷达,其差反射率因子ZDR的典型值仅为-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。在常规数字化天气雷达标定工作的基础上,进一步讨论数字化天气雷达和双线偏振雷达的标定方法以及提高标定精度的措施,对数字化天气雷达和双线偏振雷达的研究和应用有一定的参考价值。

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 ZDR is only -3 0+5 0dB and the difference of ZDR 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.
