SAR image change detection is a new field to research on the application of SAR images, which has been used in many ways successfldly, such as national economy and national defence. At present, the algorithms of SAR image change detection almost focus on singlechannel SAR image. While when muhichannels data is applied in change detection, the image information could be fully utilized, and more perfect detection result could be got. In this paper, the algorithm of change detection from muhichannel SAR image by MRF information fusion was proposed. The change detection was carried out by fusing different channels information of image. The algorithm could not only apply to the spatial reliant relationship among pixels, but fuse the different information from muhichannels. The basic principle and implementation procedure were focused on. In the end, the experimental comparison showed that the algorithm proposed in this paper could receive change detection result with very high precision.
