摘要:

天气雷达在现代气象综合观测系统中起着非常重要的作用,雷达网络能够覆盖大的空间范围,有利于雷达间的数据融合,可以更为精细地观测不同尺度的天气过程。概述了天气雷达网络技术及其应用进展,包括收发分置双(多)基地雷达网络,美国的NEXRAD和TDWR网络、欧洲的OPERA计划和中国的CINRAD网络,最后介绍最新发展的CASA网络雷达系统。较为详尽地介绍CASA网络的端对端系统、DCAS模式和数据产品,并与NEXRAD的性能进行比较。CASA能够观测中小尺度强对流系统更细微的变化,同时也是S/C波段雷达网络的有益补充。S/C波段大功率长程雷达网络与X波段小功率短程雷达网络的结合及其资料的相互

Abstract:

Weather radar plays an important part in modern comprehensive meteorological observation system.Radar network can cover large spatial dimension,which is beneficial for the data fusion and elaborately observe different scale weather phenomenons.This paper summarizes the weather radar network technology and its application progress,including the bistatic radar network,Americar NEXRAD and TDWR network,European OPERA plan and china CINRAD network,finally the ultramodern CASA radar network.An exhaustive introduction about CASA network is presented,including the end-to-end system,DCAS mode,data product and specification comparison with NEXRAD.CASA can depict more detail change of the meso microscale weather,which provides helpful supplement to for large radar network.The mutual complementation and data fusion of the high-power,long-range S/C-band radar network and the low-power,short-range X-band radar network are the development tendency in the future.

Key words: Radar network    NEXRAD    TDWR    OPERA    CINRAD    CASA
