摘要
:SAR图像一般都存在相干斑点噪声 ,严重影响了地物信息的提取与SAR图像的应用效果。文中在分析斑点噪声产生机理的基础上提出了一种噪声消除算法 ,该算法与最常用的均值平滑滤波、中值平滑滤波、Frost自适应滤波等方法相比具有更明显的效果 ,实验结果验证了本算法的有效性。
Synthetic Aperture Radar (SAR) images are usually corrupted by speckle noise. In order to suppress the speckle noise and improve interpretation of the images, an algorithm has been proposed in the paper based on the mechanism of speckle noise generating. Compared with the most popular algorithm, such as the median filter, the average filter and the Frost adaptive filter, this algorithm is more efficiently. Experimental results show that this algorithm is available.
