【摘要】 利用SAR影像所包含的相位和强度信息,将相干系数与幅度特性相结合,通过逐步回归的方法,建立了以后向散射系数、相关系数和相干系数为因子的地震破坏程度的评估模型。以该模型为基础,对青海玉树地震进行了受灾评估。更多还原

【Abstract】 Using SAR image’s phase and intensity information,and combining the coherence coefficient and SAR intensity,this paper build a new assessment model,which contains backscatter coefficient,correlation index and coherence coefficient with the method of stepwise regression.Based on this new model,we assess the building damage degree of the 2010 Yushu earthquake.更多还原
