摘要
本文基于相关系数法,以建三江与佳木斯两部新一代天气雷达为例,对两部雷达定标前后天气过程基数据进行解析,通过典型天气过程中两部雷达扫描重合地区回波概率密度、网格化散点图、强度分布图等多种图形图表进行回归统计分析,验证基于数理统计的相关系数法,对依据雷达气象方程的回波强度定标具有良好的指导效果。
Take the new generation weather radars of Jiansanjiang and Jiamusi as reference and bases on correlation coefficient method,the system parameters affecting radar echo and the causes of echo inconsistency are analyzed.Through the regression statistical analysis of the probability density,grid scatter plot and the echo intensity distribution profile of the two radars scanning coincidence area in typical weather process,the verification of correlation coefficient method is based on mathematical statistics,it shows that the method has good effect.
