Automatic target recognition (ATR) using Synthetic Aperture Radar (SAR) imagery is investigated in this paper. According to the imaging model of SAR image, a SAR ATR based on fusion of target contour and shadow contour is proposed. Firstly, this paper presents a SAR image segmentation method based on marker-controlled, by using which the target contour and the shadow contour of SAR image are obtained. Then, fusion recognition is performed by using these two kinds of contours. The effectiveness of the proposed algorithm is verified by experimental results on MSTAR. The experiments verify that the fusion of these two kinds of contours contains not only the structural information of target but also the height information of SAR target. Compared with the feature of the target contour or the shadow contour when they are used separately，the feature of the fusion of them is more steady.
