We first research how speckle in sar images influences the modes obtained from sar images by emd . we found that speckle in sar images influences the first and the second mode . the speckle filter and multiscale edge detection technique are proposed respectively based on the effects of speckle on the modes 这一章首先简要介绍了emd方法，以真实sar图像数据和模拟数据分析了斑点对emd各个模态的影响；以此为基础，研究了基于emd方法的sar图像多尺度边缘提取和斑点滤波方法。
