This article researches extraction arithmetic for missile bullet' multiple targets. Above all  enactment threshold of area  acquire middle axes of target by adopting Hough transforming and approximating and calculate obliquity angles of targets. In course of matching  accomplish missile bullet's multiple targets data association of serial images by making use of improving eigenfunction and achieve extraction of missile bullet's multiple targets after obtaining center position of targets  adopting OSTU method change numeral image into binary image  according to area of target  forecast searching region of target matching by using Kalman filter  area of targets  and abstract separately center position of targets and area of targets  judge conglutination and obstruct  then separate targets in term of wave crest and trough's variety of grey histogram of conglutination region  grey average of target and obliquity angles of targets. The experimental result shows that right ratio of the extraction targets reach to 90%. The article use correct mathematical model and reasonable arithmetic and obtain effectively parameter of missile bullet' multiple targets. 2010 IEEE.  at the same time  obtain grey average of target  mark target region
