摘要
在二维极坐标多卜勒雷达资料上建立径向速度折叠线,通过对折叠线的特征分析,判定折叠区域,进而确定每个库的径向速度值。用该算法已在多幅台风和暴雨等强天气过程的资料上对库间折叠和整体折叠实现了完全正确的退折叠处理,其优点是只对折叠区附近区域作处理,时效高、速度快,与面向径向处理的算法相比可靠性更高。
A Doppler velocity dealiasing algorithm is described that tracks aliased lineson full PPI data, and determines each bin's Nyquist Number by analysing the character-istics of the aliased line. The algorithm works well on the data of typhoons and severestorms on which there are many aliased areas. It has the advantages of high efficiencyand full consideration.
