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.
