英文摘要：

Polarimetric Synthetic Aperture Radar （PolSAR） is a promising remote sensing technique because it carries abun- dant scattering information of targets. First of all,the methods and algorithms of target extraction from PolSAR image are sum- marized and categorized, and then the new progresses made in different ways are introduced. At last the problems and challenges in this field are highlighted and some possible future works are explained.
