In this paper, the technique and development about joint retrieval of a tmospheric wind by dual-Doppler radar are proposed. Then, including the advantag es and deficiencies, the methods and courses of development about the joint retr ieval of atmospheric wind by dual-Doppler radar are described. From this paper, we can know the new technique about the joint retrieval of atmospheric wind by d ual-Doppler radar-the synthesis and continuity adjustment te chnique （MUSCAT）.
