The integrated mosaic technique of new generation Doppler weather redar network was applied in the CHeRES experiment.The technique includes the processing and conversion of radar volume scanning data,the uniform processing of radar network data,the strategy to make radar data mosaics for different bands,the wind field retrieving and the composite result display.Also based on this technique,the application software system was developed,which was used for the ovlume scanning data obtained from vari-type radars in the CHeRES experiment in 2001 and 2002,and some data mosaic results are given.
