英文摘要：

In this paper, technique of pattern recognition based on rough set and support vector machine, combined with the airplane recognition for optical remote sensing images is analyzed and researched. A classifier based on the advantage of rough set and directed acyclic graph support vector machines（DAGSVM） is designed. By means of comparable research and result analysis of classifier, some satisfied research fruit is obtained. A pattern recognition classifier based on rough set and support vector machine is designed in this paper and the classified arithmetic based on rough set and DAGSVM combined with R-DAGSVM. As a result, this method provides a high recognition precision and speed with high capability of anti-disturbance to improve the performances of classifier effectively.
