The Automatic Acquirement of Target's Region-of-Interest from SAR for the Application of Earth Observation

GAO Gui1,3, ZHANG Jun3, ZHOU Diefei2, JIANG Yongmei1, LI Deren4(1.School of Electronic Science and Engineering, NUDT, Changsha, Hunan 410073, China;2. Hunan Normal University, Changsha, Hunan 410081, China; 3.School of Information System and Management, NUDT, Changsha, Hunan 410073, China; 4.Wuhan University, Wuhan, Hubei 430079, China)  
A new scheme of the automatic acquirement of target's region-of-interest (ROI) by utilizing SAR images on the study of earth observation is proposed based on a simple review on the progress and the analysis of existing problems. The new scheme consists of a scheme of target detection and that of target discrimination. The key techniques of the new scheme are also developed. The experiment results of real SAR scenes show that the presented scheme has the characteristics of strong robustness, extensive practicability, high automatic on low computation and easy realization. Therefore, the presented scheme has the extensive prospect for spatial earth observation.
