摘　　要：多时相SAR变化检测技术,通过分析同一区域不同时相的SAR数据可以检测地表地物目标的变化信息,在土地资源调查及监测管理方面具有广泛应用。本文将长时间SAR图像相干性特征与目标幅度信息进行融合,并采用多时相SAR数据堆栈处理方法进行大区域城建目标分类及变化信息检测。最后采用13景ALOS PALSAR数据对中国天津地区2007~2010年期间的城建区域变化进行了检测实验,得到了良好的实验结果,并验证方法有效性。Muhitemporal SAR change detection has wide applications. The different acquisition SAR can be analyzed to detect the change information of the ground cover targets, which can be used for earth source manage and environment monitor. In this paper, the image coherence characteristics and amplitude information have been fused, and the multitemporal SAR data stacking method has been applied to retrieve and detect the man - made targets classifications and change information for urban constructing areas. 13 scenes L- band ALOS PALSAR images have been studied in the experiment to retrieve the urban change detection information in Tianjin area, which gives excellent detecting results and also well validate the method efficiency.
