| 摘 要： | 天气雷达数据三维格点化是天气雷达组网拼图的基础，本文研究了几种把球坐标系下的分辨率不均匀的雷达反射率资料（dBZ）插值到统一的分辨率均匀的笛卡尔坐标系下的方法，并采用模拟的天气雷达回波数据对这几种方法进行了比较分析，主要对空间反射率强度值的连续性及是否保留了雷达资料中原始的反射率结构特征进行对比分析。

| Abstract: | The foundation of multiple-radar reflectivity mosaics is the Three-Dimensional gridding of weather radar data.This paper investigates several approaches to remapping the poor resolution reflectivity fields onto a unified high-resolution 3D Cartesian coordinate system， moreover， various interpolation schemes were evaluated by the simulated weather radar echoes，mainly for the continuity of space reflectance intensity value and whether to retain the reflectivity of the radar data in the original structure characteristics were analyzed. |
